LESSON 1:
DEFINITION AND IMPORTANCE OF
AGRICULTURE
What is Agriculture?
Nominal Definition (explains what a name is)
Agriculture comes from the Latin words ager, agri meaning field and
cultura meaning growing, cultivation. Therefore it means “growing and
cultivating of the field.”
Real Definition (explains what a thing is)
Agriculture is the science or practice of farming which includes the
cultivation of the soil for the growing of crops and fruit-bearing trees. It also
considers the raising of animals to provide food and other raw materials which
can produce another product.

8
Elements in the Definition of Agriculture
 It is a science, because of systematically organized body of knowledge
which not only based on opinions, hypothesis and theories but on factual
and absolute knowledge. Also, it is a practice because of the actual
applications of the ideas.
 Of farming, because is the act or process of working the ground,
planting seeds, and growing edible plants. It can also include raising
animals for milk, meat and wool.
VALUE OF AGRICULTURE
Agriculture has a vital role in the life and progress of an economy. It
does provide food which is the basic needs of mankind, not only to sustain food
and raw material but also employment opportunities to a vast number of the
population of a country. It can be a source of livelihood which can contribute to
micro and macro community, supplying and sustaining food and fodder that are
the basic necessities of human to live, promoting the diplomatic friendship
facilitated by trading system in local, national and international arena,
marketable surplus products, source of saving of the entire national budget and
basis of the economic development of a country.
Without agriculture, the economy will be at high risk to food security
that may result into serious national problems. The effect may be adverse or
even worse.

9
Activity
Direction: Answer the following questions.
1. What is the definition of agriculture? Justify.
2. Cite a value of agriculture that without it can create serious national
problem.

LESSON 2:
BRIEF HISTORY OF AGRICULTURE
Agriculture was developed at least 10,000 years ago, and it has
undergone significant developments since the time of the earliest cultivation.
Ancient Origins
The Fertile Crescent of the Middle East was the site of the earliest
planned sowing and harvesting of plants that had previously been gathered in
the wild. Independent development of agriculture occurred in northern and
southern China, Africa's Sahel, New Guinea and several regions of the
Americas. Barley has been found in archeological sites in Levant, and East of
the Zagros Mountains in Iran.
The eight so-called Neolithic founder crops of agriculture includes
emmer wheat einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick
peas and flax. Bitter vetch and lentils along with almonds and pistachios appear
in Franchthi Cave Greece simultaneously, about 9,000 BC. Neither was native

11
to Greece, and they appear 2,000 years prior to domesticated wheat in the same
location. This suggests that the cultivation of legumes and nuts preceded that of
grain in some Neolithic cultures.
By 7,000 BC, small-scale agriculture reached Egypt. From at least 7,000
BC the Indian subcontinent saw farming of wheat and barley, as attested by
archaeological excavation at Mehrgarh in Balochistan.
By 6,000 BC, mid-scale farming was entrenched on the banks of the
Nile. About this time, agriculture was developed independently in the Far East,
with rice, rather than wheat, as the primary crop. Chinese and Indonesian
farmers went on to domesticate taro and beans including mung, soy and azuki.
To complement these new sources of carbohydrates, highly organized net
fishing of rivers, lakes and ocean shores in these areas brought in great volumes
of essential protein. Collectively, these new methods of farming and fishing
inaugurated human population boom dwarfing all previous expansions, and it
continues today.
By 5,000 BC, the Sumerians had developed core agricultural techniques
including large scale intensive cultivation of land, mono-cropping, organized
irrigation, and use of a specialized labour force, particularly along the
waterway now known as the Shatt al-Arab, from its Persian Gulf delta to the
confluence of the Tigris and Euphrates. Domestication of wild aurochs and
mouflon into cattle and sheep, respectively, ushered in the large-scale use of
animals for food/fiber and as beasts of burden. The shepherd joined the farmer
as an essential provider for sedentary and semi-nomadic societies. Maize,
manioc, and arrowroot were first domesticated in the Americas as far back as
5,200 BC.
The potato, tomato, pepper, squash, several varieties of bean, tobacco,
and several other plants were also developed in the New World, as was
extensive terracing of steep hillsides in much of Andean South America. The
Greeks and Romans built on techniques pioneered by the Sumerians but made
few fundamentally new advances. Southern Greeks struggled with very poor

12
soils, yet managed to become a dominant society for years. The Romans were
noted for an emphasis on the cultivation of crops for trade.
Middle Ages
During the Middle Ages, Muslim farmers in North Africa and the Near
East developed and disseminated agricultural technologies including irrigation
systems based on hydraulic and hydrostatic principles, the use of machines and
the use of water raising machines, dams, and reservoirs. They also wrote
location-specific farming manuals, and were instrumental in the wider adoption
of crops including sugar cane, rice, citrus fruit, apricots, cotton, artichokes,
aubergines, and saffron. Muslims also brought lemons, oranges, cotton,
almonds, figs and sub-tropical crops such as bananas to Spain. The invention of
a three field system of crop rotation during the Middle Ages, and the
importation of the Chinese-invented moldboard plow, vastly improved
agricultural efficiency. Another important development towards the end of this
period was the discovery and subsequent cultivation of fodder crops which
allowed over-wintering of livestock.
Modern Era
After 1492, a global exchange of previously local crops and livestock
breeds occurred. Key crops involved in this exchange included the tomato,
maize, potato, cocoa and tobacco going from the New World to the Old, and
several varieties of wheat, spices, coffee, and sugar cane going from the Old
World to the New. The most important animal exportations from the Old
World to the New were those of the horse and dog (dogs were already present
in the pre-Columbian Americas but not in the numbers and breeds suited to
farm work). Although not usually food animals, the horse (including donkeys
and ponies) and dog quickly filled essential production roles on western
hemisphere farms.
By the early 1800s, agricultural techniques, implements, seed stocks and
cultivated plants selected and given a unique name because of its decorative or

13
useful characteristics had so improved that yield per land unit was many times
seen in the Middle Ages. With the rapid rise of mechanization in the late 19th
and 20th centuries, particularly in the form of the tractor, farming tasks could
be done with a speed and on a scale previously impossible. These advances
have led to efficiencies enabling certain modern farms in the United States,
Argentina, Israel, Germany, and a few other nations to output volumes of high
quality produce per land unit at what may be the practical limit.
The Haber-Bosch method for synthesizing ammonium nitrate
represented a major breakthrough and allowed crop yields to overcome
previous constraints. In the past century agriculture has been characterized by
enhanced productivity, the substitution of labor for synthetic fertilizers and
pesticides, selective breeding, mechanization, water pollution, and farm
subsidies. In recent years there has been a backlash against the external
environmental effects of conventional agriculture, resulting in the organic
movement.
Agricultural exploration expeditions, since the late nineteenth century,
have been mounted to find new species and new agricultural practices in
different areas of the world.

15
LESSON 3:
BRANCHES OF AGRICULTURE
BRANCHES OF AGRICULTURE
There are four main branches of agriculture, namely;
1. Livestock Production or Animal Husbandry
2. Crop Production or Agronomy
3. Agricultural Economics
4. Agricultural Engineering
I. Livestock Production or Animal Husbandry
Animal Husbandry is the branch of agriculture concerned with animals
that are raised for meat, fiber, milk, eggs, or other products. The term
"livestock" encompasses many species and numerous breeds within animal
species which can produce food and other raw materials.
Livestock production or Animal Husbandry has 4 common classifications such
as:

16
a.) Nomadic Pastoralism is the husbandry of grazing animals is viewed as an
ideal way of making a living and the regular movement of all or part of the
society is considered a normal and natural part of life. Pastoral nomadism is
commonly practice where climatic conditions produce seasonal pastures but
cannot support sustained stationary agriculture because of the animals’ food
limitations.
b.) Poultry Farming is the raising of birds domestically or commercially,
primarily for meat and eggs as well as for feathers. Chickens, turkeys, ducks,
and geese are of primary importance, while guinea fowl and squabs (young
pigeons) are chiefly of local interest.

17
c.) Swine Farming is the raising and breeding of domestic pigs as livestock,
and is a branch of animal husbandry. Pigs are farmed principally for food (e.g.
pork, bacon, gammon) or sometimes skinned.
d.) Apiculture is the scientific method of rearing honeybees. The word
‘apiculture’ comes from the Latin word apis meaning bee and colere which
means “to culture”. Bees are mainly reared for their honey. So, apiculture or
also known as beekeeping is the care and management of honey bees for the
production of honey and the wax. In this method of apiculture, bees are bred
commercially in apiaries, an area where a lot of beehives can be placed.
Apiaries can be set up in areas where there are sufficient bee pastures – usually
areas that have flowering plants.

18
II. Crop Production or Agronomy
It is the science dealing with the cultivation of crops and vegetables on a
field scales either under rain fed or irrigation conditions. These crops are
mainly annuals cultivated food. The requirements of each crop are studied in
terms of soil and climate, as well as planting time and techniques, different
cultivars, fertilization, weed, disease, and insect control, as well as the effect of
stress factors. Crop Production or Agronomy includes:
Horticulture is the science and art of growing and caring for plants,
especially flowers, fruits, and vegetables. The word is derived from the Latin
hortus which means “garden” and colere which means “to culture”. As a
general term, it covers all forms of garden management, but in ordinary use it
refers to intensive commercial production. Horticulture has 3 branches namely,
pomology, olericulture and floriculture.

19
a) Pomology- is the branch of botany that studies all fruits, specifically the
science of growing fruits and nuts. The word is derived from the Latin
pomum which means “fruit” and logia which means “field of study”. As a
branch of horticulture, it focuses to the cultivation of fruits, nuts, fruit-
bearing and nut-bearing trees/plants for human use and consumption.
b) Olericulture is the science and art of vegetable growing, dealing with the
culture of non-woody (herbaceous) plants for food. The word is derived
from the Latin oleris which means “pot herb” and colere which means “to
culture”. As language develops over long period of time, it is simply
defined as the science and art of growing vegetables crops. It deals with the
production, storage processing and marketing of vegetables. It encompasses
crop establishment, including cultivar selection, seedbed preparation and
establishment of vegetable crops by seed and transplants. It also includes
maintenance and care of vegetable crop production.

20
c) Floriculture refers to farming, plant care, propagation, and cultivation with
one goal in mind, the maximum production of flowering and ornamental
plants for gardens and floristry, comprising the floral industry. The word is
derived from the Latin floris which means “flower” and colere which
means “to culture”. Therefore, it is the cultivation of flower. To elaborate,
floriculture is an entire gardening spectrum that is geared towards
understanding and improving all aspects of bud and flower creation,
including indoor lighting, growroom requirements, greenhouse needs, plant
nutrition, irrigation, pest management, and breeding new cultivars/strains.
III. Agricultural Economics is study of the allocation, distribution and
utilization of the resources used, along with the commodities produced, by
farming. It concerns itself with the study of the production and consumption of
food in both developed and developing countries along with analysis of the
policies that shape the world’s largest country.

21
IV. Agricultural Engineering is the area of engineering concerned with the
design, construction and improvement of farming equipment and machinery.
Agricultural engineers integrate technology with farming. For example, they
design new and improved farming equipment that may work more efficiently,
or perform new tasks. They design and build agricultural infrastructure such as
dams, water reservoirs, warehouses, and other structures. They may also help
engineer solutions for pollution control at large farms. Some agricultural
engineers are developing new forms of biofuels from non-food resources like
algae and agricultural waste. Such fuels could economically and sustainably
replace gasoline without jeopardizing the food supply.

22
Activity
Direction: Answer the following questions. Write your answer on one whole
piece of yellow pad paper.
1. What are the four (4) branches of agriculture? Give its importance.
2. What are the four (4) branches of livestock production? Describe

LESSON 4:
TYPES OF AGRICULTURAL CROPS
AND ITS CLASSIFICATIONS
Agricultural crops are plants that are grown or intentionally managed by
man for certain purposes. They are classified in various terms used worldwide.
Types of Crops
Crops are divided into six falls into categories and they’re as follows:
1. Food Crops
2. Feed Crops
3. Fiber Crops
4. Oil Crops
5. Ornamental Crops
6. Industrial Crops

24
Descriptions of Crops According to their Categories
I. Food Crops – A plant that is primarily raise, culture and harvest for the
human consumption. It has two sub categories, the field crops and root
crops.
a) Field crop is a crop (other than fruits or vegetables) that is grown on a
large scale for agricultural purposes. Examples are wheat, rice, corn,
sugarcane and other forage crops. These crops typically consist of a
large majority of agricultural acreage and crop revenues.
b) Root Crops – are underground plant parts edible for human
consumption.

25
II. Feed Crops – A plant that is primarily raise, culture and harvest for the
livestock consumption.
III. Fiber Crops – A plant that is primarily raise, culture and harvest for its
fibers which are used as raw material.
IV. Oil Crops – A plant that is primarily raise, culture and harvest as base
for biodiesel production.

26
V. Ornamental Crops – A plant that is primarily raise and culture for
decorative purposes especially in gardens and landscape design projects.
VI. Industrial Crops – A plant that is cultured for their biological materials
which are used in industrial processes into nonedible products.
(Example: Tobacco)

27
Classification of Crops According to their Reproduction
1. Sexual - plants that develop from a seed or a spore after undergoing
union of male and female gametes.
2. Asexual – plants which reproduce by any vegetative means without the
union of the sexual gametes.

28
Classification of Crops According to Mode of Pollination
I. Naturally Self Pollinated Crops – predominant mode of pollination in
this plant is self-pollination.
II. Naturally Cross Pollinated Crops – pollen transfer in these plants is
from another of one flower in a separate plant.

29
III. Both Self and Cross Pollination Crops – these plants are largely self-
pollinated but in varying amounts.
Classifications of Crops According to Growth Habits
I. Herb – succulent plants with self-supporting stems.
II. Vines – herbaceous climbing or twining plants without self-supporting
stem.

30
III. Lianas – woody climbing or twining plants which depend on other
plants for vertical support to climb up to the tree.
IV. Shrubs – a small tree or tree like plants generally less than 5 meters in
height but other authorities restricted to small, erect woody plants.

31
V. Trees – plants having erect and continuous growth with a large develop
of woody tissue, with a single distinct stem or trunk.
VI. Evergreen – plants that maintain their leaves throughout the year.
VII. Deciduous – plants which naturally shed off or lose leaves annually for
extended periods.

32
Descriptions of Crops According to their Life Span
I. Annual crop is a plant that completes its life cycle, from germination to
production of seed, within one growing season, and then dies. Annual
crops examples are rice, corn and others.
II. Biennial crop is a plant that takes two years to complete its biological
lifecycle. Its examples are cabbage, parsley and others.

33
III. Perennial crop is a plant that lives more than two years. The term is
often used to differentiate a plant from shorter-lived annuals and
biennials. The term is also widely used to distinguish plants with little or
no woody growth from trees and shrubs, which are also technically
perennials.

major categories of common commercial crops in the Philippines they are the
following: cereal crops, root and tuber crops, sugar crops, vegetable crops, fruit
crops.

36
a) Cereal Crops – are one of the members of grass family with their seed
to eat.
b) Root and Tuber Crops – a crop that is root vegetables and thick
underground part of the stem which is edible to consume by human.
c) Sugar Crops – several species of tall perennial grass that are grown for
extraction of sugar product.

37

LESSON 6:
PLANT PARTS AND ITS FUNCTION
A plant has different parts. The main parts are the roots, stem and the
leaves. Each part has a vital role in the life of a plant. The root absorbs water
and different nutrients in the ground. The roots also establish the plant as
foundation. The stem carries the water and different nutrients from the ground
to the leaves. It also supports the foundation.
The Roots

41
The main functions of the root system are absorption of water and
minerals from the soil, providing a proper anchorage to the plant parts, storing
reserve food material and synthesis of plant growth regulators.
In majority of the dicotyledonous plants, the direct elongation of
the radicle leads to the formation of primary root which grows inside the soil.
It bears lateral roots of several orders that are referred to as secondary, tertiary,
and so on. The primary roots and its branches constitute the tap root system.
In monocotyledonous plants, the primary root is short lived and is
replaced by a large number of roots. These roots originate from the base of the
stem and constitute the fibrous root system.

42
In some plants, roots arise from parts of the plant other than the radicle
and are called adventitious roots.
The root is covered at the apex by a thimble-like structure called
the root cap. It protects the tender apex of the root as it makes its way through
the soil.
Tap roots of carrot, turnip and adventitious roots of sweet potato, get
swollen and store food.

43
Hanging structures that support a banyan tree are called prop roots.
Similarly, the stems of maize and sugarcane have supporting roots
coming out of the lower nodes of the stem. These are called stilt roots.
In some plants such as Rhizophora growing in swampy areas, many

44
roots come out of the ground and grow vertically upwards. Such roots,
called pneumatophores, help to get oxygen for respiration.
The Stem
The stem of a plant is one of two structural parts of a vascular plant (a plant
that has tissues for moving water and nutrients), the other being the root. The
stem is the part above ground which provides support for leaves and buds. It's
like the major highway of a plant, and it's vital for plant life.
The region of the stem where leaves are born are called nodes while
internodes are the portions between two nodes. Some stems perform the
function of storage of food, support, protection and of vegetative propagation.

45
Underground stems of potato, ginger, turmeric, zaminkand,
colocasia are modified to store food in them.
Stem tendrils which develop from axillary buds, are slender and
spirally coiled and help plants to climb such as in gourds (cucumber, pumpkins,
watermelon) and grapevines.

46
Axillary buds of stems may also get modified into woody, straight
and pointed thorns. They protect plants from browsing animals.
Some plants of arid regions modify their stems into flattened (Opuntia),
or fleshy cylindrical (Euphorbia) structures. They contain chlorophyll and carry
out photosynthesis.
Underground stems of some plants such as grass and strawberry, etc.,
spread to new niches and when older parts die new plants are formed

47
The Leaf
Leaf is a flattened structure of a higher plant, typically green and blade-
like, that is attached to a stem directly or via a stalk. Leaves are the main
organs of photosynthesis and transpiration.
Leaves originate from shoot apical meristems. Leaf develops at the
node and bears a bud in its axil. The axillary bud later develops into a branch.

48
A typical leaf consists of three main parts: leaf base,
petiole and lamina. The petiole help hold the blade to light. Long thin flexible
petioles allow leaf blades to flutter in wind, thereby cooling the leaf and
bringing fresh air to leaf surface. The lamina or the leaf blade is the green
expanded part of the leaf with veins and veinlets. There is, usually, a middle
prominent vein, which is known as the midrib. Veins provide rigidity to the
leaf blade and act as channels of transport for water, minerals and food
materials.
Leaf Venation
The arrangement of veins and the veinlets in the lamina of leaf is termed
as venation. When the veinlets form a network, the venation is termed
as reticulate. When the veins run parallel to each other within a lamina, the
venation is termed as parallel. Leaves of dicotyledonous plants generally

49
possess reticulate venation, while parallel venation is the characteristic of
most monocotyledons.
Modifications of Leaves
Leaves of certain insectivorous plants such as pitcher plant, venus-fly
trap are also modified leaves for their food.
Transpiration
Plants absorb mineral nutrients and water from the soil. Not all the water
absorbed is utilised by the plant. The water evaporates through the stomata
present on the surface of the leaves by the process of transpiration. The
evaporation of water from leaves generates a suction pull (the same that you
produce when you suck water through a straw) which can pull water to great
heights in the tall trees. Transpiration also cools the plant.

50
Water absorption through roots can be increased by keeping the plants
a. in the shade
b. in dim light
c. under the fan
d. covered with a polythene bag
When we place a plant under the fan the speed of air flow is very high.
Transpiration will take place in presence of high air flow through the stomata.
Rate of transpiration increases during windy condition. Increase in the rate of
transpiration increases the water absorption also because when transpiration
occurs, it will create a transpiration pull and more water absorption will take
place.
Do Plants Also Respire?
In plants each part can independently take in oxygen from the air and
give out carbon dioxide. Even roots can respire. Can you guess what would
happen if a potted plant is overwatered? Plants carry out photosynthesis only
during the day and respiration both during the day time as well as night.
Did you know? For us oxygen is essential, but for those organisms which do
not use it, oxygen is toxic. In fact, our white blood cells use oxygen to kill
invading bacteria. Even for humans, it may be dangerous to breathe pure
oxygen for long.

51
The Flower
The flower is the reproductive unit in the angiosperms. It is meant for
sexual reproduction. Androecium and gynoecium are reproductive organs.
When a flower has both androecium and gynoecium, it is bisexual. A flower
having either only stamens or only carpels is unisexual. Aestivation: The
mode of arrangement of sepals or petals in floral bud with respect to the other
members of the same whorl is known as aestivation.
Parts of a Flower

52
Androecium
Androecium is composed of stamens. Each stamen which represents the
male reproductive organ consists of a stalk or a filament and an anther. Each
anther is usually bilobed and each lobe has two chambers, the pollen-sacs. The
pollen grains are produced in pollen-sacs. A sterile stamen is called staminode.
Gynoecium
Gynoecium is the female reproductive part of the flower and is made up
of one or more carpels. A carpel consists of three parts namely stigma, style
and ovary. After fertilization, the ovules develop into seeds and the ovary
matures into a fruit. Placentation: The arrangement of ovules within the ovary
is known as placentation.

53
The Fruit
The fruit is a characteristic feature of the flowering plants. It is a mature
or ripened ovary, developed after fertilisation. If a fruit is formed without
fertilisation of the ovary, it is called a parthenocarpic fruit. The ovules after
fertilization, develop into seeds.
Transport Of Water And Minerals In Plants
Plants absorb water and minerals by the roots. The roots have root hair.
The root hair increase the surface area of the root for the absorption of water
and mineral nutrients dissolved in water. The root hair is in contact with the
water present between the soil particles.
Plants have pipe-like vessels to transport water and nutrients from the
soil. The vessels are made of special cells, forming the vascular tissue. The
vascular tissue for the transport of water and nutrients in the plant is called

54
the xylem. The xylem forms a continuous network of channels that connects
roots to the leaves through the stem and branches and thus transport water to
the entire plant leaves synthesise food. The food has to be transported to all
parts of the plant. This is done by the vascular tissue called the phloem. Thus,
xylem and phloem transport substances in plants.

LESSON 1:
SELECT AND USING FARM TOOLS
FARM TOOLS IN AGRICULTURAL CROP PRODUCTION
Farm tools, implements, and equipment play very important role in
agricultural crop production. Their availability makes the work much easier
and faster. However, even if one may have the most sophisticated tools and
implements, but does not know how to use them, they are useless. In order to
do crop production operations successfully, one must have a good working
knowledge of the tools, implements and equipment before using them.
Hand Tools
Hand tools are usually light and are used without the help of animals or
machines. They are being used in performing farm activities which involve
small areas like school garden and home garden. Examples:

66
Axe is for cutting bigger size post.
Bolo is used for cutting tall grasses and weeds and chopping branches of
trees.
Crowbar is used for digging big holes and for digging out big stones
and stumps.

67
Grab-hoe is used for breaking hard topsoil and pulverizing soil.
Hand Cultivator is used for cultivating the garden plot by loosening the
soil and removing weeds around the plant.
Hand Fork is used for inter row cultivation.

68
Hand Trowel is used for loosening the soil around the growing plants
and putting small amount of manure fertilizer in the soil.
Knife is for cutting planting materials and for performing other
operations in horticulture.

69
Light Hoe is used for loosening and leveling soil and digging out
furrows for planting.
Pick-mattock is used for digging canals, breaking hard topsoil and for
digging up stones and tree stumps.
Pruning Shears is for cutting branches of planting materials and
unnecessary branches of plants.

70
Rake is used for cleaning the ground and leveling the topsoil.
Shovel is used in removing trash, digging loose soil, moving soil from
one place to another and for mixing soil media.
Sickle is a hand-held agricultural tool with a variously curved blade
typically used for cutting weeds.

71
Spade is used for removing trash or soil, digging canals or ditches and
mixing soil media.
Spading Fork is used for loosening the soil, digging out root crops and
turning over the materials in a compost heap.
Sprayers are for spraying insecticides, foliar fertilizers, fungicides and
herbicides.

72
Sprinkler is for watering seedlings and young plants.
Wheel barrow is used for hauling trash, manures, fertilizers, planting
materials and other equipment.
Water Pail is for hauling water, manure and fertilizers.

73
Farm Implements
These are accessories which are being pulled by working animals or
mounted to machineries (hand tractor, tractor) which are usually used in the
preparation of land. These are usually made of a special kind of metal.
Examples:
Native Plow
Disc Plow
Plows are farm implements either pulled by a working animal or a
tractor. The plow is specifically used for tilling large areas, making furrows and
inter row cultivation. Plows pulled by working animals are made of either a
combination of metal and wood or pure metal. They are used to till areas with a
shallower depth than that of the disc plows which are pulled by tractors.

74
Native Wooden Harrow
Disc Harrow
Harrows are used for tilling and pulverizing the soil. The native
wooden harrow is made of wood with metal teeth and pulled by a carabao
while the disc harrow is made of metal mounted to a tractor.

LESSON 3:
PERFORM MAINTENANCE
PRE-OPERATIVE CHECK UP OF FARM TOOLS AND EQUIPMENT
Imagine that the long, hot summer vacation has finally come to an end
and it‘s the beginning of the school year and you are ready to start working
your vegetable gardens. But before that let us check first our tools, implements
and equipment you are going to use.
Grab with your working clothes and personal protective equipment
(PPE). Proceed to the shop to retrieve your tools so that you can start clearing
away the last remnants of summer and begin tools to see that they are covered
with rust and dirt that has hardened and crusty globs of oil that have collected
dust last vacation. It seems that you are going to spend more time cleaning
breaking the soil for a new year. Imagine your frustration as you start pulling
out all of your and repairing tools on this nice day than you will actually use
them.

82
How to Clean Your Tools and Equipments:
Let‘s start with the basics. Your shovel, spade, hoe, or even the blades
on a hedge trimmer will be a lot easier to use if you take a few minutes to
knock some of the rust off the blade. Not only will this extend the life of the
tool, but also it will cut through the soil better, and thus require less effort to
use, if it has a nice sharp blade.
It is a good idea to keep a large whetstone in your shop. A whetstone is
an ideal tool to use to keep all of the cutting edges of your garden tools honed.
It will work well on your pruning shear, as well as many other common garden
tools.

83
The best way to use the stone is to find a way to stabilize the tool that
you want to work on. A bench vise is ideal. You will be able to clamp the tool
into place at an angle, so you can work on it. Clamping the garden tool into
place with a vise frees up both of your hands to use the whetstone and gives
you more control over what you are doing. Apply a little bit of lubricating oil to
the end of the tool and carefully begin to work the stone over the blade.
Maintain a 30-degree angle between the stone and the blade to form the ideal
cutting edge for your tool. Not only will the edge become sharper, but you will
also be removing any pitting and rust that has formed at the edge of your tool‘s
blade.
In instances where the moving parts of your garden tools (such as with
of any new pruners, shears, and loppers) have frozen in place, like springs and
pivot joints, you should disassemble them first carefully break free any rust or
dirt that may keep the tool from functioning properly. Clean accumulated rust

84
and dirt off all metal surfaces with a wire brush. Remove stubborn rust from
small tools with fine steel wool. Using an old toothbrush with some lightweight
lubricating oil is a great way to work fresh oil into the joints of most garden
tools. Not only will this fresh oil helps your tool to work as it was intended, but
it will also prevent the formation of rust. Use medium-grit sandpaper to remove
rust on larger tools such as shovels, spades, and hoes.
Once your tools are cleaned, they're ready to be sharpened. When
sharpening, try to maintain the original factory bevel or angle. For pruners, use
a whetstone because it produces a very sharp cutting edge. Depending on the
type of whetstone, apply a few drops of oil or water to the stone. With the
beveled side of the blade against the stone, rub the sharp edge of the blade
toward the stone in a curved motion, as if you were trying to shave off a thin
slice from the stone.
When working with a file, stabilize the blades in a vise or against a solid
surface such as a work bench to avoid injury and ensure an even stroke.

85
Always push the file across the blade in a motion away from your body. Move
the file diagonally, so that its cutting teeth are biting into the metal on the tool.
When sharpening with a file, do not use oil; metal filings will accumulate and
clog the file's serrations.
Farm implements like ordinary plow and wooden harrow should be
checked thoroughly before use. Loosened bolts and nuts should be tightened
firmly. Disc plow and harrow should also be lubricated on their moving parts
like bearings. Tractors should be tuned-up very well by skilled operator. Check
on their oil, lubricant, fuel and cooling system.

86
Activity
WELL-MAINTAINED, WELL EFFECTIVE
Direction: Bring the following materials and tools needed. Perform the
procedures properly.
Materials:
 1 Bottle/Container of Any Industrial Oil
 A piece of Rag
 Pieces of Sand Paper 300
 PPE such as gloves, eye protector goggles or glasses and dust mask
Tools:
 A set of Hedge Shear
 A set of Metal Clamp
 A Pile
 A Wrench (the size is based from the pivot nut of the hedge shear)
 A Bench Vise (look for School Facilities if available)
Procedure:
Step 1: Safety First. Wear all your Personal Protective Equipments. Prevention
to an accident is better than cure.
Step 2: Tighten the pivot nut. Before sharpening, check the pivot nut. It could
be loose, making the blades drift apart while cutting and tearing the twig
instead of cutting it clean. The nut should be snug with no play in the pivot.
With the nut tightened, check the tool; if it cuts cleanly, it doesn't need
sharpening. If it still cuts poorly, look down each blade to make sure it's not
bent. If a blade is slightly bent, loosen the pivot nut and separate the blades. To

87
straighten the blade, put it in a vise, slip on some thick leather gloves and
tweak it until it's straight.
Step 3: Hold the metal clamp using a vise. Examine the factory edge. Hold the
pile with both hands and mimic the direction of the bevel. Move the pile in one
direction, away from you. Don't use small, jerky strokes or you'll lose the
factory edge. As you work, you can see the clean metal path left by the pile.
Adjust your angle as needed to pile the entire edge evenly. Repeat this motion
several times until you expose clean metal over the whole edge. Usually it'll
take only about 10 strokes. Do the same with the other blade.
Step 4: Sand the back side of the blade. Place a sheet of 300-grit wet/dry
sandpaper on a smooth, flat piece of plywood. You'll be able to feel the burrs
(be careful— they're sharp) on the back side of each blade caused by the filing
action. To remove them, lightly sand the back side of the blade. Keep the blade
flat and move it in a circular motion. After making several circles, pick up the

FARM INPUTS AND LABOR
FARM INPUTS
They are defined as products permitted for use in organic farming.
These include feedstuffs, fertilizers and permitted plant protection products.
The resources that are used in farm production. The following are examples:
Seed is a material which is used for planting or regeneration purpose.
However scientifically, it is a fertilized matured ovule together covered with

89
seed coat and it is a propagating material. Thus, seed is the most vital and
crucial input for crop production.
Fertilizer is a chemical or natural substance added to soil or land to
increase its fertility. There are two types of fertilizer; organic and inorganic.
Pesticide is a substance used for destroying insects or other organisms
harmful to cultivated plants or animals.
FARM LABOR
Farm labor is the manpower to perform agricultural works such as land
preparation, planting, sowing, plant caring, maintenance, harvesting, and
storing. It is the comprehensive efforts by an individual or group of men to
successfully fulfill the needs of the demand of farm operations.

LESSON 1:
BASIC WORKPLACE CALCULATIONS
PERFORM CALCULATION
It is important to be able to measure and calculate surface areas. It might be
necessary to calculate, for example, the surface area of the cross-section of a
canal or the surface area of a farm.
This section will discuss the calculation of some of the most common surface
areas: triangle, square, rectangle, rhombus, parallelogram, trapezium and circle.

105
The height (h) of a triangle, a rhombus, a parallelogram or a trapezium,
is the distance from a top corner to the opposite side called base (b). The height
is always perpendicular to the base; in other words, the height makes a "right
angle" with the base. An example of a right angle is the corner of this page.
In the case of a square or a rectangle, the expression length (1) is
commonly used instead of base and width (w) instead of height. In the case of a
circle the expression diameter (d) is used.
The height (h), base (b), width (w), length (1) and diameter (d) of the
most common surface areas
TRIANGLES
The surface area or surface (A) of a triangle is calculated by the formula:
A (triangle) = 0.5 x base x height = 0.5 x b x h

106
Triangles can have many shapes but the same formula is used for all of them.
SQUARES AND RECTANGLES
The surface area or surface (A) of a square or a rectangle is calculated
by the formula: Area=Length x Width
In a square the lengths of all four sides are equal and all four angles are
right angles. In a rectangle, the lengths of the opposite sides are equal and all
four angles are right angles. All lengths and widths in a square are equal. All
lengths and widths in a rectangle are not equal.
RHOMBUSES AND PARALLELOGRAMS
The surface area or surface (A) of a rhombus or a parallelogram is calculated
by the formula: Area= Base x Height

107
In a rhombus the lengths of all four sides are equal; none of the angles are right
angles; opposite sides run parallel. In a parallelogram the lengths of the
opposite sides are equal; none of the angles are right angles; opposite sides run
parallel.
TRAPEZIUMS
The surface area or surface (A) of a trapezium is calculated by the formula:
Area=0.5 (Base+Top) x Height
The top (a) is the side opposite and parallel to the base (b). In a
trapezium only the base and the top run parallel.
Another method to calculate the surface area of a trapezium is to divide
the trapezium into a rectangle and two triangles, to measure their sides and to
determine separately the surface areas of the rectangle and the two triangles.
Splitting a trapezium into one rectangle and two triangles.
Note that A = A1+ A2 + A3 = 1 + 6 + 2 =9 cm2

108
CIRCLES
The surface area or surface (A) of a circle is calculated by the formula:
Area=1/4(3.14x d2
)
Whereby d is the diameter of the circle and ¶ (a Greek letter,
pronounced Pi) a constant (¶ = 3.14). A diameter (d) is a straight line which
divides the circle in two equal parts.
METRIC CONVERSIONS
The basic unit of length in the metric system is the meter (m). One meter can
be divided into 10 decimeters (dm), 100 centimeters (cm) or 1000 millimeters
(mm); 100 m equals to 1 hectometer (hm); while 1000 m is 1 kilometer (km).
1 m = 10 dm = 100 cm = 1000 mm
0.1 m = 1 dm = 10 cm = 100 mm
0.01 m = 0.1 dm = 1 cm = 10 mm
0.001 m = 0.01 dm = 0.1 cm = 1 mm
1 km = 10 hm = 1000 m
0.1 km = 1 hm = 100 m
0.01 km = 0.1 hm = 10 m
0.01 = 0.01 hm = 1 m

109
Units of surface
The basic unit of area in the metric system is the square meter (m),
which is obtained by multiplying a length of 1 meter by a width of 1 meter.
1 Surface Area in Hectare (ha)=100m x 100m= 10 000m2
A square meter
1 m2
= 100 dm2
= 10 000 cm2
= 1 000 000 mm2
0.01 m2
= 1 dm2
= 100 cm2
= 10 000 mm2
0.0001 m2
= 0.01 dm2
= 1 cm2
= 100 mm2
0.000001 m2
= 0.0001 dm2
= 0.01 cm2
= 1 mm2
1 km2
= 100 ha2
= 1 000 000 m2
0.01 km2
= 1 ha2
= 10 000 m2
0.000001 km2
= 0.0001 ha2
= 1 m2
SURFACE AREAS OF CANAL CROSS-SECTIONS AND FARMS
This Section explains how to apply the surface area formulas to two
common practical problems that will often be met in the field.

110
DETERMINATION OF THE SURFACE AREAS OF CANAL CROSS-
SECTIONS
The most common shape of a canal cross-section is a trapezium or, more truly,
an "up-side-down" trapezium.
Canal Cross Section
The area (A B C D), hatched on the above drawing, is called the canal
cross-section and has a trapezium shape. Thus, the formula to calculate its
surface is similar to the formula used to calculate the surface area of a
trapezium:
Surface area of the canal cross-section= 0.5 (base + top line) x canal depth
=0.5 (b +a) x h
Whereby:
base (b) = bottom width of the canal
top line (a) = top width of the canal
canal depth (h) = height of the canal (from the bottom of the canal to the top of
the embankment)

111
Wettted Cross-Section of a Canal
The area (A B C D), hatched on the above drawing, is called the wetted
canal cross-section or wetted cross-section. It also has a trapezium shape and
the formula to calculate its surface area is:
Surface area of the wetted canal cross-section = 0.5 (base + top line) x water
depth = 0.5 (b + a1) x h1
Whereby:
base (b) = bottom width of the canal
top line (a1) = top width of the water level
water depth (h1) = the height or depth of the water in the canal (from the
bottom of the canal to the water level).
DETERMINATION OF THE SURFACE AREA OF A FARM
It may be necessary to determine the surface area of a farmer's field. For
example, when calculating how much irrigation water should be given to a
certain field, the size of the field must be known.
When the shape of the field is regular and has, for example, a
rectangular shape, it should not be too difficult to calculate the surface area
once the length of the field (that is the base of its regular shape) and the width
of the field have been measured.

112
Field of regular shape
Field of irregular shape
In this case, the field should be divided in several regular areas (square,
rectangle, triangle, etc.).

113
Division of irregular field into regular areas
Surface area of the square: As = length x width = 30 m x 30 m = 900 m2
Surface area of the rectangle: Ar = length x width = 50 m x 15 m = 750 m2
Surface area of the triangle: At = 0.5 x base x height = 0.5 x 20 m x 30 m = 300
m2
Total surface area of the field: A = As + Ar + At = 900 m2
+ 750 m2
+ 300 m2
=
1950 m2
INTRODUCTION TO VOLUME
A volume (V) is the content of a body or object. Take for example a
block. A block has a certain length (l), width (w) and height (h). With these
three data, the volume of the block can be calculated using the formula:
V (block) = length x width x height = l x w x h

114
UNITS OF VOLUME
The basic unit of volume in the metric system is the cubic meter (m3
)
which is obtained by multiplying a length of 1 meter, by a width of 1 meter and
a height of 1 meter.
One cubic meter
1m3
= 1.000 dm3
= 1 000 000 cm3
= 1 000 000 000 mm3
0.001 m3
= 1 dm3
= 1 000 cm3
= 1 000 000 mm3
0.000001 m3
= 0.001 dm3
= 1 cm3
= 1 000 mm3
0.000000001 m3
= 0.000001 dm3
= 0.001 cm3
= 1 mm3
VOLUME OF WATER ON A FIELD
Suppose a one-liter bottle is filled with water. The volume of the water
is 1 liter or 1 dm3
. When the bottle of water is emptied on a table, the water will
spread out over the table and form a thin water layer. The amount of water on
the table is the same as the amount of water that was in the bottle.
The volume of water remains the same; only the shape of the "water
body" changes.

115
One Liter of water spread over a table
A similar process happens if you spread irrigation water from a storage
reservoir over a farmer's field.
A volume of 100 m3
of water spreas over an area of one hectare
The formula to use is:
As the first step, the volume of water must be calculated. It is the
volume of the filled reservoir, calculated with formula:
Volume (V) = length x width x height = 5 m x 10 m x 2 m = 100 m3
As the second step, the thickness of the water layer is calculated using
formula:

116
Given
Surface of the field = 10 000 m2
Volume of water = 100 m3
Formula: d= Volume of Water (m3
)
Surface of the Field (m2
)
Answer: d= 100 (m3
)
10 000 (m2
)
d = 0.01 m or d = 10 mm
A water layer 1 mm thick is spread over a field of 1 ha. Calculate the
volume of the water (in m3
).
One millimeter water depth on a field of one hectare
The formula to use is:
Volume of water (V) = Surface of the field (A) x Water depth (d)
Given:
Surface of the field = 10 000 m2
Water depth = 1 mm =1/1 000 = 0.001m
Answer:
Formula: Surface of the field (m²) x water depth (m)
Volume (m3)
V = 10 000 m2
x 0.001 m
V = 10 m3
or 10 000 liters

117
INTRODUCTION TO FLOW-RATE
The flow-rate of a river, or of a canal, is the volume of water discharged
through this river, or this canal, during a given period of time. Related to
irrigation, the volume of water is usually expressed in liters (l) or cubic meters
(m3
) and the time in seconds (s) or hours (h). The flow-rate is also called
discharge-rate.
CALCULATION AND UNITS
The water running out of a tap fills a one liter bottle in one second. Thus the
flow rate (Q) is one liter per second (1 l/s).
A flow-rate of one liter per second
PROBLEM
The water supplied by a pump fills a drum of 200 liters in 20 seconds.
What is the flow rate of this pump?
The formula used is: Q= Flow-Rate (l/s)= Volume of Water (liters)
Time (seconds)
Given: Volume of water: 200 L
Time: 20s
Answer: Q= Volume of Water_ =200l= 10 l/s
Time 20s

118
The unit "liter per second" is commonly used for small flows, e.g. a tap
or a small ditch. For larger flows, e.g. a river or a main canal, the unit "cubic
metre per second" (m3
/s) is more conveniently used.
PROBLEM
A river discharges 100 m3
of water to the sea every 2 seconds. What is
the flow-rate of this river expressed in m3
/s?
The formula used is: Q= Flow-Rate (m3
/s)= Volume of Water (m3
)
Time (seconds)
Given: Volume of water: 100 m3
Time: 2s
Answer: Q= Volume of Water_ =200m3
= 50 m3
/s
Time 2s
The discharge rate of a pump is often expressed in m3
per hour (m3
/h) or
in liters per minute (l/min).
Formula: Q = Flow-Rate (l/min) = Volume of Water (litres)
Time (minutes)
or
Q = Flow-Rate (m3
/h) = Volume of Water (m3
)
Time (hours)

119
INTRODUCTION TO PERCENTAGE
In relation to agriculture, the words percentage will be met regularly.
For instance "60 percent of the total area is irrigated during the dry season". In
this Section the meaning of the word "percentage" will be discussed.
PERCENTAGE
The word "percentage" means literally "per hundred"; in other words
one percent is the one hundredth part of the total. You can either write percent,
or %, or 1/100, or 0.01.
Some examples are:
5 percent = 5% =5/100 = 0.05
20 percent = 20% = 20/100= 0.20
25 percent = 25% = 25/100 = 0.25
50 percent = 50% = 50/100 =0.50
100 percent = 100% = 100/100 = 1
150 percent = 150% = 150/100 = 1.5
QUESTION
How many oranges are in 1% of a total of 300 oranges?
Three oranges are in 1% of 300 oranges

120
ANSWER
1% of 300 oranges = 1/100 x 300 = 3 oranges
INTRODUCTION TO GRAPHS
A graph is a drawing in which the relationship between two (or more)
items of information (e.g. time and plant growth) is shown in a symbolic way.
To this end, two lines are drawn at a right angle. The horizontal one is
called the x axis and the vertical one is called the y axis.
Where the x axis and the y axis intersect is the "0" (zero) point.
The plotting of the information on the graph is discussed in the following
examples.
A graph
EXAMPLE 1
Suppose it is necessary to make a graph of the growth rate of a corn
plant. Each week the height of the plant is measured. One week after planting
the seed, the plant measures 2 cm in height, two weeks after planting it
measures 5 cm and 3 weeks after planting the height is 10 cm.

121
Measuring the growth rate of a corn plant
These results can be plotted on a graph. The time (in weeks) will be
indicated on the x axis; 2 cm on the axis represents 1 week. The plant height (in
centimeters) will be indicated on the y axis; 1 cm on the axis represents 1 cm of
plant height.
After 1 week the height is 2 cm; this is indicated on the graph with A;
after 2 weeks the height is 5 cm, see B, and after 3 weeks the height is 10 cm,
see C.
At planting (Time = 0) the height was zero, see D.
Now connect the crosses with a straight line. The line indicates the
growth rate of the plant; this is the height increase over time.
It can be seen from the graph that the plant is growing faster and faster
(during the first week 2 cm and during the third week 5 cm); the line from B to
C is steeper than the line from D to A.

122
Graph of the growth rate of a corn plant
From the graph can be read what the height of the plant was after, say 2
1/2 weeks; see the dotted line. Locate on the horizontal axis 2 1/2 weeks and
follow the dotted line upwards until the dotted line crosses the graph. From this
crossing follow the dotted line to the left until the vertical axis is reached. Now
take the reading: 7.5 cm, which means that the plant had a height of 7.5 cm
after 2 1/2 weeks. This height has not been measured in reality, but with the
graph the height can be determined anyway.
QUESTION
What was the height of the plant after 1 1/2 weeks?
ANSWER
The height of the plant after 1 1/2 weeks was 3.5 cm.
EXAMPLE 2
Another example to illustrate how a graph should be made is the
variation of the temperature over one full day (24 hours). Suppose the outside
temperature (always in the shade) is measured, with a thermometer, every two
hours, starting at midnight and ending the following midnight.
Suppose the following results are found:

123
Time(hr) Temperature(°C)
0 16
2 13
4 6
6 8
8 13
10 19
12 24
14 28
16 2
18 27
20 22
22 19
24 16
Graph showing temperature over 24 hours; mistake 16 hour reading
On the x axis indicate the time in hours, whereby 1 cm on the graph is 2
hours. On the y axis indicate the temperature in degrees Celsius (°C), whereby
1 cm on the graph is 5°C.
Now indicate (with crosses) the values from the table (above) on the
graph paper and connect the crosses with straight dotted lines.

124
Graph showing temperature over 24 hours; estimated correction of mistake
At this stage, if you look attentively at the graph, you will note that there
is a very abrupt change in its shape around the sixteenth hour. The outside
temperature seems to have fallen from 28°C to 2°C in two hours‘ time! That
does not make sense, and the reading of the thermometer at the sixteenth hour
must have been wrong. This cross cannot be taken in consideration for the
graph and should be rejected. The only dotted line we can accept is the straight
one in between the reading at the fourteenth hour and the reading at the
eighteenth hour.
Graph showing temperature over 24 hours; smooth curve
In reality the temperature will change more gradually than indicated by
the dotted line; that is why a smooth curve is made (continuous line). The

125
smooth curve represents the most realistic approximation of the temperature
over 24 hours.
From the graph it can be seen that the minimum or lowest temperature
was reached around 4 o'clock in the morning and was about 6°C. The highest
temperature was reached at 4 o'clock in the afternoon and was approximately
29°C.
QUESTION
What was the temperature at 7, 15 and 23 hours? (Always use the smooth curve
to take the readings).
ANSWER
Temperature at 7 hours: 10°C

LESSON 1:
FARM PLANS AND LAYOUT
The Farming for the Future (FFTF) program can help you to plan the
best farm layout. It is an initiative of NSW Government agencies focusing on
whole farm planning. A whole farm plan considers the farm‘s physical,
financial and human/personal resources for both now and the future.
Site assessment
An on-site assessment of a farm is necessary so that a map can be drawn
of the property‘s topography, boundaries, soils, water resources and so on, and
a farm business plan can be formulated.
Government plans
Acquaint yourself with relevant Regional Environmental Plans (REPs),
Local Environmental Plans (LEPs), and Development Control Plans (DCPs)

136
and their short and long-term effects on your proposed or existing farm
enterprise. This will help reduce unforeseen risks and enhance your farm
business. Council‘s building approval or development consent (DAs) may be
needed for siting greenhouses, siting and constructing dams or erecting hail and
windbreak netting. Council approval to clear land or a no burning of crop
debris or waste materials on farm‘ may apply. Consent will be required if odor
or noise is a nuisance likely to be generated from the development.

How Crops are Arranged in Row Planting
Row planting as applied in conventional horizontal farming or
gardening is asystem of growing crops in linear pattern in at least one direction
rather than planting without any distinct arrangement. It is practiced in most
crops whether direct seeded, transplanted or grown from vegetative planting
materials, both in monocropping and multiple cropping.
Crops are planted in rows or straight lines, either singly or in multiple
rows, mainly to enhance maximum yields as well as for convenience. An east-
west row orientation is preferred to maximize light absorption, but this is not
always possible. In many cases the topography that includes the shape, terrain
and slope of the land, as well as the location of existing vegetation, roads,
irrigation lines, buildings and physical barriers, dictate the row orientation.
The specific advantages of row planting over broadcasting or scatter
planting include the following: (1) light absorption is maximized and,
conversely, the excessive shading effect of other plants is minimized thus
favoring more efficient photosynthesis and improved crop yield; (2) wind
passage along the interrows is enhanced which increases gas exchanges and
prevents excessive humidity; (3) access through the interrows facilitates
cultivation, weeding, and other farm operations including hauling; (4)
movement within the crop area is convenient and allows close inspection of
individual plants; and (5) visibility is enhanced.
Row Planting Arrangement

139
Row-planted crops are either arranged in equidistant single rows or in
multiple rows. Planting insingle rowsis most common in monocropping or
sole cropping, the growing of a single crop.
Different systems of planting arrangement within the row are practiced
in both single and multiple row planting, depending on the characteristics and
requirement of the crop, particularly its extent of canopy expansion. In the hill
method of plantingcrops by direct seeding, the crops are arranged, singly or in
group, in uniform distances. But in the drill method, the only consideration is a
uniform number ofplants per linear meter.
In row-planted fruit trees and other perennial crops like coconut, oil
palm and rubber, the common types of planting or spatial arrangement are the
square, rectangular, quincunx, and triangular or hexagonal.
Multiple Row Planting Arrangement

140
Multiple row planting is a system of growing crops in blocks or strips of
2 or more rows. The adjacent blocks are separated by a space which may
remain vacant or planted to other crops. This planting arrangement is common
in multiplecropping in which two or more crops are grown in the same piece
of land. It is alsoemployed in monocropping where an alley wide enough to
facilitate passage is needed.
Coconut and other perennial crops are often intercropped with multiple
rows of annual crops like corn and pineapple. This is a common practice of
maximizing the use of vacant interrow spaces when the maincrop has not fully
developed thus allowing sufficient light exposure. In some farms, the intercrop
consists of multiple rows of such crops as coffee, cacao and banana. In this
system, both single row planting (for the maincrop) and multiple row planting
(for the intercrop) are combined.
In vegetable production that employs close spacing and where crops
should be within easy reach, the common practice is to plant in plots having
multiple rows. A space between plots is provided to allow passage.
Spatial Arrangement in Intercropping
Spatial arrangement is the systematic apportioning of the farm area or
anygrowing surface for crop production. In multiple cropping by intercropping,
the intercrop can be planted in any of the following ways: (1) within the rows
of the maincrop, (2) between the rows of the maincrop, and (3) in replacement
series Planting of the intercrop between two adjacent hills within the same row
of the main crop allows interrow cultivation but the intercrop has limited
exposure to sunlight. This is exemplified by the planting of peanut or
mungbean between corn plants within the same row or two coffee plants that
are 3 m apart between coconut plants.
Single row planting of the intercrop can also be done between the rows
of the maincrop. For example, peanut or mungbean can be dibbled between two
adjacent rows of corn. This system of planting arrangement is likewise

141
common in coconut farms where fruit trees like durian, lanzones and
mangosteen are grown in single rows between coconut.
In replacement series, one or more rows that are intended for the
maincrop are replaced with the intercrop. For example, a 3:2 corn+mungbean
intercrop means that for every 4 rows that are intended for sole corn, only 3
rows are planted to corn and one row may be substituted with 2 rows of
mungbean. Another practice is in strip intercropping, for example the
simultaneous growing of 6 rows corn and 12rows soybean in alternating strips.
These particular examples result to multiple row planting arrangement.
Methods of Planting Crops in the Farm
In general, there are two methods of planting crops: direct seeding and
transplanting. Direct seeding is either by broadcast, hill or dibble, or by drill
method. The hill and the drill methods are alternative options in row planting.
Direct Seeding
Direct seeding or direct sowing is a method of planting in which seeds
are directly planted on the ground in the farm or any growing surface. It
generally applies to large-seeded vegetables as well as in cereals and grain
legumes.The term direct seeding is also commonly used to refer to the planting
of seedpieces or underground vegetative planting materials directly into the
soil.

142
Planting crops by broadcasting or sabog tanim, or scatter planting,
commonly applies to small seeds, like rice and mungbean, that are capable of
germination and sustained growth without soil cover. There is no control of
plant-to-plant spacing. The seeds are simply distributed on a well prepared
ground by hand or with a mechanical broadcaster.
With hand broadcasting, a volume of seeds is held by the hand and
thrown with a wide swath. Skill is important to ensure even distribution of
seeds per unit ground area based on the desired seeding rate per hectare. For
example, a seeding rate of 100 kg per hectare means that the seeds have to be
distributed at an average of 0.01 kg or 10 g per sq meter. Assuming that the
crop is rice with a weight of 1000 grains of 29 grams, this is equivalent to a
seeding rate of about 345 seeds per sq meter.
Excessive seeding per unit area will mean that the prepared seeds will
have been completely sown but a portion of the farm is still unplanted, and so
additional seeds need to be procured. Conversely, seeding below the average
will complete the planting of the entire farm with some seeds still left.
In lowland rice, the seeds are broadcasted on puddled soil or over water
and allowed to germinate without covering. The broadcast method of planting
crops is also common with mungbean and cowpea grown as green manure. But
in upland farming, it is best to pass a tooth harrow or rake after broadcasting to
cover the seeds. The soil covering will hide the seeds from seed-harvesting
organisms like chicken and birds. It will also ensure that the seeds have full
contact with the soil which will maximize germination and improve the chance
of the seedlings to fully develop. In pasture establishment, a large herd of
livestock can be released after broadcasting to press the seeds into the ground
by their hooves. Dibbling is an old method of planting crops practiced by
subsistence farmers in hilly lands.
In both the hill and drill methods of planting crops by direct seeding,
there is a desired row-to-row spacing. Hills with a single or multiple number of
plants are spaced uniformly within each row so that in the hill method there is
always a reference to hill distance and number of plants per hill. A hill is that

143
specific spot on the ground on which a plant or a group of plants is grown. In
contrast, there is no uniform spacing between plants in the row in the drill
method, but uniformity in number of plants per linear meter is intended.
The hill method of direct seeding is done by dropping seeds in holes
made by a dibbler or in furrows that are more or less equidistant. But with
mechanized farming, a combine furrower-planter is commonly used.
In planting corn under rainfed conditions at a population density of, for
instance, 60,000 plants per hectare at 1 plant per hill in rows 70 cm apart, the
farmer walks forward along a furrow and drops a seed every 23.8 cm to the
bottom of the furrow. He does not carry a measuring tool, he just estimates
distances on the ground with impressive accuracy borne of long experience. To
cover the seeds, he merely sweeps the ridge at either side of the furrow by one
foot to push some soil toward the seed and steps thereon to press the soil on top
of the seed.
The drill method of planting crops is done, either manually or
mechanically, by releasing seeds continuously, as if pouring water from a
bottle with a small opening. Manual drilling applies to small seeds like rice,
millet, and mungbean and is usually done by hand. It can also be accomplished
by placing small, roundish seeds in a bottle with a hole on the cover. The seeds
are simply released by tilting and slightly shaking the bottle so that the seeds
drop one after the other or in a cascade through the hole and toward the ground.
The seeds are drilled with or without furrows. In rice, drilling in puddled
soil in linear direction is a modification of seed broadcasting in which plants
are dispersed without plant-to-plant spacing. But in rainfed sorghum,
mungbean, and other grain legumes, the seeds are always drilled at the bottom
of the furrow, covered with soil by raking or by foot, and stepped on to press
the soil.
Just like in the hill method of planting crops, an even distribution of
drilled seeds is intended but varies with the seeding rate per hectare and row
distance. With a seeding rate of 100 kg per hectare in rows 20 cm apart, the
calculated average seeding rate per linear meter in the row is 2 grams. With

144
1000 grain weight of 29 grams for rice, this is equivalent to a seeding rate of
about 70 seeds per linear meter. But if the row distance is widened to 25 cm,
the average seeding rate will increase to 2.5 grams or 86-87 seeds per linear
meter.
Transplanting
The term transplanting is also used to refer to the practice of replanting
an already established plant in one location and moving it elsewhere. It is a
method of planting in which makes use of pre-grown plants, seedlings or
vegetatively propagated clones. Transplanting is most common with small-
seeded vegetables, vegetatively propagated crops, ornamental crops, fruit trees
and many perennial crops.
Transplanting is also convenient with a few plants that can be
transferred with a ball of soil around the roots. In some vegetables, it is
common to prick seedlings from the seedbed and transplant them bareroot to
the garden plot. In perennial species like coffee at a time when rainfall has
become frequent and light is not intense, uprooted wildlings or bareroot
transplants have been directly planted.

LESSON 2:
PLAN AND DESIGN
IRRIGATION SYSTEM PLAN AND DESIGN
Water required by crops is supplied by nature in the form of
precipitation, but when it becomes scarce or its distribution does not coincide
Several irrigation methods are available, and the selection of one depends on
factors such as water availability, crop, soil characteristics, land topography,
and associated cost.
Proper design of an irrigation system requires that the pumping system
precisely match to the irrigation distribution system so that the pressure and
flow rate required can be efficiently provided by the pumping system. The
energy required to pump water is determined by the total dynamic head (water
lift, pipe friction, system pressure, etc.), the water flow rate desired and the
pumping system's efficiency.

148
Irrigation water management involves determining when to irrigate, the
amount of water to apply at each irrigation event and during each stage of
plant, and operating and maintaining the irrigation system. The main
management objective is to manage the production system for profit without
compromising environment and in agreement with water availability. A major
management activity involves irrigation scheduling or determining when and
how much water to apply, considering the irrigation method and other field
characteristics.
FUNCTIONS OF FARM IRRIGATION SYSTEMS
The primary function of farm irrigation systems is to supply crops with
irrigation water in the quantities and at the time it is needed. Specific function
includes:
1. Diverting water from the water source.
2. Conveying it to individual fields within the farm.
3. Distributing it within each field.
4. Providing a means for measuring and regulating flows.
Other functions of farm irrigation system include crop and soil cooling,
protecting crops from frost damage, delaying fruit and bud development, and
controlling wind erosion,
providing water for seed germination, application of chemicals, and land
application of wastes.
REASONS FOR AN IRRIGATION PLAN
 A project plan enables the designer to lay out the irrigation system in the
most cost effective way. The plan is used to generate a material list and
to evaluate the anticipated project costs.
 The plan provides step by step information on system installation.
Information on crop spacing, sprinklers, pumping requirements, pipeline
sizes and lengths should be included on the plan. Pertinent obstructions

149
such as roads, trees, gas, oil, water, telephone or transmission lines must
also be indicated.
 Specification, design standards and work schedules as set out on a plan
form the basis of any contractual agreements between the installation
contractor and the farmer.
 The plan provides a record for future reference. It can be used for
overall farm planning and identifies limits of expansion potential.
ESSENTIAL FEATURES OF A PLAN
 Topographic Data - the field shape must be accurately drawn showing
pertinentobstructions, features and elevation details.
 Water Source Capacity - the water supply must be clearly
indicatedshowing location and available capacity.
 Depending on the water source, a well log or water license must
accompany the irrigation plan. Irrigation reservoirs also require Water
Management Branchlicensing.
 Soil and Crop Characteristics - soil and crop limitations must be
accounted for toreduce runoff and deep percolation by mismanagement
of the irrigation system.
 Design Parameters - soil water holding capacity, maximum application
rate andclimatic data must be used to select the correct irrigation system
design.
 Design Data - the nozzle selected, operating pressure, discharge rate
and sprinklerspacing must all be shown on the plan. The irrigation
interval, set time, application rate and net amount applied must also be
calculated.

150
DIFFERENT DESIGNS OF IRRIGATION SYSTEMS
1. SURFACE IRRIGATION- water is applied to the field in either the
controlled or uncontrolled manner.
Surface irrigation consisted of:
1.1 Furrow system
A. FURROW IRRIGATION BY CUTTING THE RIDGE

151
B .FURROW IRRIGATION WITH SIPHONS
The Major Design Considerations in Surface Irrigation Include:
1. Storing the readily available moisture in the root zone, if possible;
2. Obtaining as uniform water application as possible;
3. Minimizing soil erosion by applying non-erosive streams;
4. Minimizing runoff at the end of the furrow by using a re-use system or a
cut –back stream;
5. Minimizing labor requirements by having good land preparation,
6. Good design and experienced labor and
7. Facilitating use of machinery for land preparation, cultivation,
furrowing, harvesting etc.
1.2 Border Irrigation System
1. In border irrigation, controlled surface flooding is practiced whereby the
field is divided up into strips by parallel ridges or dikes and each strip is

152
irrigated separately by introducing water upstream and it progressively
covers the entire strip.
2. Border irrigation is suited for crops that can withstand flooding for a
short time e.g. wheat.
3. It can be used for all crops provided that the system is designated to
provide the needed water control for irrigation of crops.
4. It is suited to soils between extremely high and very low infiltration
rates.
5. In border irrigation, water is applied slowly.
6. The root zone is applied with water gradually down the field.
7. At a time, the application flow is cut-off to reduce water loses.
8. Ideally, there is no runoff and deep percolation.
9. The problem is that the time to cut off the inflow is difficult to
determine.
Design Parameters of Border Irrigation System
a) Strip width: Cross slopes must be eliminated by leveling.
Since there are no furrows to restrict lateral movement, any cross
slope will make water move down one side leading to poor application
efficiency and possibly erosion.
-The stream size available should also be considered in choosing
a strip width.
-The size should be enough to allow complete lateral spreading
throughout the length of the strip.
-The width of the strip for a given water supply is a function of
the length -The strip width should be at least bigger than the size of
vehicle tract for construction where applicable.
b) Strip Slope: Longitudinal slopes should be almost same as for the
furrowirrigation.

153
c) Construction of Levees: Levees should be big enough to withstand
erosion,and of sufficient height to contain the irrigation stream.
d) Selection of the Advance Stream: The maximum advance stream used
shouldbe non-erosive and therefore depends on the protection afforded
by the crop cover. Clay soils are less susceptible to erosion but suffer
surface panning at high water velocities. Table 3.4 gives the maximum
flows recommendable for bare soils.
e) The Length of the Strip: The ideal lengths can be obtained by field
tests.
1.3 Basin Irrigation System
Characteristics:
1. In basin irrigation, water is flooded in wider areas. It is ideal for
irrigating rice.
2. The area is normally flat.
3. In basin irrigation, a very high stream size is introduced into the basin so
that rapid movement of water is obtained.
4. Water does not infiltrate a lot initially.
5. At the end, close the water inlet to avoid water loss in the pond.
6. The opportunity time difference between the upward and the downward
ends are reduced.

154
7. The size of basin is related to stream size and soil type.
Suggested basin areas for different soil types and rates of water flow
Flow rate Soil Type
Sand Sandy loam Clay loam Clay
l/s m3
/hr Hectares
30 108 0.02 0.06 0.12 0.20
60 216 0.04 0.12 0.24 0.40
90 324 0.06 0.18 0.36 0.60

240 864 0.16 0.48 0.96 1.60
300 1080 0.20 0.60 1.20 2.00
Note: The size of basin for clays is 10 times that of sand as the
infiltration rate forclay is low leading to higher irrigation time. The size of
basin also increases as the flow rate increases. The table is only a guide and
practical values from an area should be relied upon. There is the need for field
evaluation.

155
2. SPRINKLER IRRIGATION
The sprinkler system is ideal in areas where water is scarce.
A Sprinkler system conveys water through pipes and applies it with a
minimum amount of losses.
 Water is applied in form of sprays sometimes simulating natural rainfall.
 The difference is that this rainfall can be controlled in duration and
intensity.
 If well planned, designed and operated, it can be used in sloping land to
reduce erosion where other systems are not possible.
Components of a Sprinkler Irrigation System
Types of Conventional Sprinkler Systems
a) Fully portable system: The laterals, mains, sub-mains and the pumping
plantare all portable.
The system is designed to be moved from one field to another or other
pumping sites that are in the same field.

156
b) Semi-portable system: Water source and pumping plant are fixed in
locations.Other components can be moved.
The system cannot be moved from field to field or from farm to farm
except when more than one fixed pumping plant is used.
c) Fully permanent system: Permanent laterals, mains, sub-mains as well
as fixedpumping plant. Sometimes laterals and mainlines may be buried.
The sprinkler may be permanently located or moved along the lateral. It
can be used on permanent irrigation fields and for relatively high value
crops e.g. Orchards and vineyards. Labor savings throughout the life of
the system may later offset high installation cost.
3. DRIP OR TRICKLE IRRIGATION
Advantages:
a) Water is applied directly to the crop ie entire field is not wetted.
b) Water is conserved
c) Weeds are controlled because only the places getting water can grow
weeds.
d) There is a low pressure system.
e) There is a slow rate of water application somewhat matching the
consumptive use. Application rate can be as low as 1 – 12 l/hr.
f) There is reduced evaporation, only potential transpiration is considered.
g) There is no need for a drainage system.

LESSON 1:
SAFETY MEASURE IN FARM OPERATIONS
APPLY APPROPRIATE SAFETY MEASURES WHILE WORKING IN
FARM
Many hazards are present in the farm. If the farmers are not aware of
these hazards these may cause injury to their body or may cause diseases and
even death. Farmer should always apply appropriate safety measures while
working in the farm. In this lesson the students with the guidance and
supervision of their teacher should identify farm works that involve the use of
chemicals and hazardous tools and equipment; determine the uses of Personal
Protective Equipment (PPE) and determine farm emergency procedures
regarding safety working environment.
HAZARD, RISK AND EXPOSURE IN THE FARM
Agricultural crop production deals with a lot of activities to be done in
the different workplace. While performing these activities we expose ourselves
to a lot of risk. Workplace hazard is a major cause of accident, injury, or harm

172
to a worker who performs such task. These hazards should be the major
concern of all who are involved in a certain job or work.
It is important to distinguish hazard, risk and exposure when
undertaking risk management.
 Hazard is the potential for harm, or adverse effect on an employee‘s
health. anything which may cause injury or ill health to anyone at or
near a workplace is a hazard.
 Risk is the likelihood that a hazard will cause injury or ill health to
anyone at or near aworkplace. The level of risk increases with the
severity of the hazard and the duration and frequency of exposure.
 Exposure occurs when a person comes into contact with a hazard.
Types of Hazard
Hazards are classified into five different types. They are:
1. Physical - includes floors, stairs, work platforms, steps, ladders, fire,
falling objects,slippery surfaces, manual handling (lifting, pushing,
pulling), excessively loud and prolonged noise, vibration, heat and cold,
radiation, poor lighting, ventilation, air quality
2. Mechanical and/or electrical - includes electricity, machinery,
equipment, pressurevessels, dangerous goods, fork lifts, cranes, hoists
3. Chemical - includes chemical substances such as acids or poisons and
those thatcould lead to fire or explosion, like pesticides, herbicides,
cleaning agents, dusts and fumes from various processes such as
welding
4. Biological - includes bacteria, viruses, mold, mildew, insects, vermin,
animals
5. Psychosocial environment - includes workplace stressors arising from
a variety ofsources.

173
Farm emergency procedures regarding safety working environment
1. Identify the potential emergencies.
The emergencies that may occur on a crop production farm could
include:
a. Fire f. snake or spider bite
b. Flood g. chemical exposure
c. Typhoon h. injuries
d. machinery entrapment i. illness
e. electrical shock j. accidents
2. Provide emergency facilities appropriate for the sorts of emergencies
that might occur on the farm (e.g. deluge showers, eye washes, fire
fighting equipment, first aid kits).
3. Make sure that the correct equipment is available to contain and handle
any chemical or other dangerous materials spills that might happen.
4. To help minimize the risk of personal injury or property damage in the
event of an emergency, people working on and visiting the farm need to
know and understand the emergency procedures and their
responsibilities.
5. Instruct everyone working on the farm in the emergency response
procedures
6. Everyone should know the location of fire alarms, fire extinguishers and
first aid kits; how and where to contact emergency services; and where
to safely assemble in the event of an emergency.
The following factors may increase risk of injury or illness for farm workers:
 Age –injury rates are highest among children age 15 and under and
adults over 65.
 Equipment and Machinery –most farm accidents and fatalities involve
machinery. Proper machine guarding and doing equipment maintenance
according to manufacturers‘ recommendation can help prevent
accidents.

174
FARM WORKS THAT INVOLVE USING CHEMICALS AND
HAZARDOUS TOOLS AND EQUIPMENT
1. Spraying Chemicals
Many different chemicals are used on a farm including pesticides. These
chemicals are used to fertilize and control pests such as insects, weeds,
mollusk, etc. Most of these chemicals are applied by spraying
Examples of chemical hazards:
a. Spraying in a strong wind and the spray drifting over a dam or the
farm house.
b. Washing spray equipment and the water running into open drains,
collecting in puddles, or running into stockyards or dams.
c. Containers or chemicals left lying around. Empty containers lying
in a heap.
Some ways you can reduce the risk of hazards from chemicals are:
 Use personal protective equipment such as respirators,
waterproof clothes, rubber gloves and waterproof footwear.
 Make sure chemicals are safely stored and cupboards locked.
 Never spray chemicals on days when there is a high wind.
 Know first aid procedures.
 Keep a list of all hazardous substances used on the farm.
Safe use of chemicals
Consider if a chemical substance is really needed.
a. Eliminate a hazardous substance, or if that is not possible,
substitute it with less hazardous one.
b. Safe work practices or personal protective equipment should be
used
c. Keep records of farm chemicals.
2. Land Preparation Using Tractor

175
a. Victims fall off or are thrown from the tractor
b. Run over by either the tractor or an implement being towed, or
both.
c. Overturn
Safety Reminders
 Use seat belts when driving tractors.
 ROPS will protect the operator from serious injuries.
Causes of run over accidents
 Sudden stops
 Driving over holes, stumps and debris, or a sharp turn
How to prevent runover
 Never allow riders on tractors.
 Discuss with family members and farm workers the potential
risks of riding tractor.
 It's also helpful to post 'no riders' decals on all tractors to remind
others about the policy.
 Use or provide other vehicles that allow passengers, such as
trucks or cars, when transportation is needed to fields or remote
work sites.
PERSONAL PROTECTIVE EQUIPMENT (PPE)
Personal protective equipment (PPE) can reduce the number and
severity of farm work related injuries and illnesses. Personal protective
equipment not only helps protect people but also improves productivity and
profits. Farmers and ranchers can share in these benefits by using the
appropriate protective equipment for themselves, family members and
employees when the job and its potential hazards call for it.

176
Hard Hat
Protect your head with a hard hat when performing construction work,
trimming trees, repairing machinery, and doing other jobs with head injury
risks. Use a sun safety hat (one with a wide brim and neck protection) to assist
in the prevention of skin cancer.
Safety Eyewear
Protect your vision with appropriate safety eyewear (safety glasses,
goggles, face-shields) when applying pesticides, fertilizers, working in the
shop, or in heavy dust conditions.

177
Earmuffs and Ear Plugs
Protect your hearing with acoustic earmuffs or plugs when operating
noisy equipment such as grain dryers, feed grinders, older tractors, chain saws,
etc.
Dust Masks, Cartridge Respirators and Gas Masks
Protect your lungs with the correct respiratory equipment when working
in dusty or moldy conditions, spray painting, applying chemicals, working in
bins, tanks, silos, and manure storage places.

178
Protective Suit
Safety Clothing is important in the workplace as it protects users against
any health and safety risk at work. It lessens the likelihood of injury, illness and
legal issues, and ensures a safe, happy working environment.
Safety Gloves
Safety Gloves are designed to keep the users’ hand from hazards
including cuts, chemical burns, abrasions, crushing or contact with bio-hazards.

179
Safety Shoes
Safety footwear is essential to ensure safe and healthy feet. Steel toe
boots and shoes protect the users’ feet, it help prevent injuries to them, and
reduce the severity of injuries that may occur in the workplace.

186
Technique in storing chemicals
Chemicals are used on farms for a variety of purposes. The safe
management of chemicals requires access to information and responsible
action. Manufacturers, suppliers and users of farm chemicals all have an
important role to play. Chemical substances present different types of risks to
people‘s health, safety and the environment. For this reason there are different
laws controlling them. The purpose of these laws is to ensure that chemicals are
used safely and efficiently so that risks to human health, the environment and
damage to property are minimized.
Safe Management of chemicals involves:
 Correct labeling and packaging;
 Provision of material safety data sheets (MSDS);
 Safe transport, storage, use and disposal of substances.
Labeling and Packaging of Chemicals
Chemicals must be supplied in packages that are correctly labeled and
suitable for the substance. Information provided on the label will depend on the
type of substance and the risks associated with it. Items to look for are:
1. Signal words such as CAUTION, POISON or DANGEROUS POISON
used for scheduled poisons – a signal word alerts users to the possibility
of poisoning if the substance is swallowed, inhaled or absorbed through
the skin.
2. The Dangerous Goods (ADG) diamond if there is an immediate risk to
health or safety e.g. flammable liquids.
3. Risk phrases describing the type of health effects e.g. irritating the skin,
and safety phrases stating precautions for safe handling, storage, spills,
disposal and fire e.g. keep away from combustible material.

187
Ensure that containers remain labeled
Farmers must ensure that the original labels remain on containers of
substances. If a substance is poured into a second container such as a spray
tank then that container must be labeled with the product name and appropriate
risk and safety phrases. These can generally be copied from the parent
container. Labeling is not necessary if a substance is used immediately and its
container is thoroughly cleaned.
There are good reasons for ensuring that proper containers and
appropriate labels were used including:
 Using food containers to store poisons can result in poisoning due to
accidental swallowing.
 Insurance companies may question liability if something goes wrong
and an unlabeled container has been the cause of an incident.
 Produce cannot be exported if maximum residues limits are exceeded
labels provide advice on permitted use and withholding periods for
agricultural and veterinary chemicals.
Material Safety Data Sheets
Material safety data sheets (MSDS) must be produced by the
manufacturer or importer of hazardous substance.
The MSDS is not just a piece of paper. It provides important and useful
advice about what is in the product, its health effects, safe use and handling,
storage, disposal, first aid and emergency operation. Farmers must obtain the
MSDS from their supplier and keep them in a register where they are available
to people who could be exposed to the hazardous substance.
The register is a collection of the MSDS and other information which
can be kept in a folder, filing cabinet or other practical system.
The register can be kept in the house, workplace or the chemical store,
so long as it remains accessible to emergency service personnel and any
employees who may be exposed to hazardous substances.

188
Storage and Transport of Chemicals
Safe storage of farm chemicals is needed to protect them from the
elements, restrict access to them, prevent contamination of the environment,
food or livestock and ensure separation from other incompatible chemicals.
Arrangements must be in place to contain any spillage of the chemical.
After considering the potential risk to people‘s health or to the
environment, a farmer might decide that a locked shed with a roof and concrete
floor, which is bounded to contain any spills, is the best way to provide safe
storage.
Remember, you should never store oxidizing agents with fuels. That is –
never store substances labeled yellow diamond with a red diamond. Safe
transport of farm chemicals depends on what the substance is, how much there
is, where it is to be transported and what else is to be transported with it. In
general, small quantities (less than 250 liters) can be transported on vehicle
provided that the container is properly secured and safe from spillage.
Disposal of Farm Chemicals
Empty farm chemical containers and unwanted chemicals need to be
disposed of properly. Prior to disposal of empty containers, wash the container
out three times and use the rinse water to dilute further batches of the chemical
to working strength.
To wash a container you do not need to fill it each time. If you only have six
liters of water, it is more efficient to use three washes of two liters each, than it
is to rinse once with the full six liters.
ENVIRONMENTAL LAWS
Presidential Decree (PD) 1152, ―the Philippine Environmental Code,
which took effect in 1977, provides a basis for an integrated waste management
regulation starting from waste source to methods of disposal. PD 1152 has
further mandated specific guidelines to manage municipal wastes (solid and
liquid), sanitary landfill and incineration, and disposal sites in the Philippines.

189
In 1990, the Philippine Congress enacted the Toxic Substances, Hazardous and
Nuclear Wastes Control Act, commonly known as Republic Act (RA) 6969, a
law designed to respond to increasing problems associated with toxic chemicals
and hazardous and nuclear wastes. RA 6969 mandates control and management
of import, manufacture, process, distribution, use, transport, treatment, and
disposal of toxic substances and hazardous and nuclear wastes in the country.
The Act seeks to protect public health and the environment from unreasonable
risks posed by these substances in the Philippines. Apart from the basic policy
rules and regulations of RA 6969, hazardous waste management must also
comply with the requirements of other specific environmental laws, such as PD
984 (Pollution Control Law), PD 1586 (Environmental Impact Assessment
System Law), RA 8749 (Clean Air Act) and RA 9003 (Ecological Solid Waste
Management Act) and their implementing rules and regulations.

LESSON 1:
DEFINITION OF FISHERY AND ITS IMPORTANCE
What is FISHERY?
As the time goes by, different centuries and generation are past. The
original term of fish were interpret by various early people. The term has a
different version to another set of people. From the Proto-Indo-European(4500
BC to 2500 BC) it is used as peysk/pisk. It was used for numbered centuries,
then, the term was again change because of the passing of generation to
generation and another generation. The term in the language of Proto-Germanic
(500 BC) was fiskaz. The term in West Frisian was fisk, in Dutch was vis, in
Danish and Norwegian was fisk, in German was fisch. Old English adopted it
and later it was coined as fisc. Today, the contemporary English now term it as
fish. In our Philipinelocal term is isda.
Fish is approximately 34,000 species of vertebrate scaly-skinned animal,
which swims and found in the fresh and salt waters of the world. It breathes

203
under the water because of their gills, absorbing the oxygen from the water to
suffice the needs of body to live. Fish is a vertebrate being because they have a
skeleton with a spine. Just like mammals, birds, reptiles and amphibians, fish
have a skeleton made from bone. But rays and sharks have a skeleton made of a
rubbery, softer substance called cartilage. A fish wiggle its tail to swim through
water. Their fins function as the steer and support their body to stay upright.
Fins are covered in skin without scale. Bony rays supported the fins to maintain
the structure and functionality of fins. A fish has an armored body by scales to
protect from the parasites and other injuries. Scales also gives the fish a
reflectors and coloration to hide and camouflage themselves from the
predators’ sight.
Fishery (plural: fisheries) is an organized effort by humans to catch fish
or other aquatic species, an activity known as fishing including the processing
and marketing as well as protecting and conserving fish and other fishery
product for sustainable use.
VALUE OF fishery
Fishery has a vital role in the life and progress of an economy. It does
provide food which is the basic needs of mankind, yet not only sustain food
and raw material but also employment opportunities to a vast number of the
population in country. It can be a source of livelihood which can lead to

204
contribute to micro and macro community; supplying, sustaining food and
fodder that are the basic necessities of human to live, promoting the diplomatic
relationship facilitated by trading system in local, national and international,
marketable surplus products, protect our environment and natural resources,
another source of savings of the entire national budget and basis of the
economic development of a country.
Without fishery, the economy will be at high risk to food security that
may be resulted into serious national problems. The above mentioned
statements may occur obverse and the opposite of those things may happen.

LESSON 2:
BRIEF HISTORY OF FISHERY
Regular eating of freshwater fish was evident in 42,000 and 39,000
years ago by the Tianyuan man. Hunter-gatherer lifestyle was the mostly work
of the people. So, they move a lot because they seek their food. The only
permanent settlement is the cave and/or shell midden. Discarded fish bone and
carved painting in the caves was supported the evidence that fishing was
occurring in the early ages. Based from the arts was observed, they hunt fish at
the salt and freshwater. One of the examples is from the Southern France, the
cave art is 16,000 years old. It represents the marine animals and spearfishing
with barbed poles also known as harpoons. Main fishing methods appearing in
the Neolithic times between 8,000 and 4,000 years ago. One of the early fishing
hooks was gorge hook used by Native Americans of the California coast
between 7,500 to 3,000 year ago. Some other tribes used plant toxins to numb
fish and fish it out easily. Harappans (people that lived during the Bronze Age
at the place of today’s archaeological site in Punjab, Eastern Pakistan,) used
one of the first bronze harpoons.

207
Ancient Egypt was famously known as the sea-side settlers and heavily
dependent to the fishing. Method of fishing used on the Nile River was shown
at their artworks which are at the wall tomb, on drawing and papyrus
documents. Ancient Egyptian fished in small reed ships Nile perch, catfish and
eels, and used woven nets, weir baskets, harpoons, and hook and line to catch
them. The first metal barbed fish hooks appeared during the 12th
dynasty.
Ancient Greeks considered fisherman of very low status so that they
depicted them in art. Despite of this, Museum of Fine Arts, Boston, has a Greek
wine cup from 500 BC that shows a boy that crouches on a rock and has a
fishing rod in his hand and a fish trap in water below him. Basically – all
civilizations that lived near the water have developed some forms of fishing
and relied on fish as a part of their diet to some extent.
It is not known when commercial fishing started but was characteristic
for it was that is used types of fishing which allowed for a larger catch. To do
that, fishermen used gillnets which existed from ancient times. Thy were used
in Middle East, North America and other places and are still used in pacific
Northwest, Canada and Alaska. Early fishermen used nets close to the coast but
with improvements in navigation and communication devices, mobility of
fishing vessels increased largely and they started conquering the oceans. Beside
fish, catch of commercial fishermen are sea cucumbers (so called “trepanging”)
for markets of Southern China and the rest of Southeast Asia.
Except primarily for food, fishing is used as recreational activity. The
first mention of recreational fishing dates from 15th
century and it comes from
essay “Treatyse of Fysshyngewyth an Angle” by dame Juliana Berners, the
prioress of the Benedictine Sopwell Nunnery. This type of fishing became
popular during the 16th
and 17th
centuries and it was performed on rivers and
lakes. When the first motorboats appeared in 19th
century, big-game fishing
started to be popular. Dr.Charles Frederick Holder, a marine biologist and early
conservationist is considered an inventor of this branch of fishing.

208
Fishing is still today popular as a sport and as part of economy of some
country. Fishery is the business of catching, handling, taking, marketing, and
preserving of the fish and other fishery products.

LESSON 3:
BRANCHES OF FISHERY
BRANCHES OF FISHERY
There are 3 branches of fishery and they are follows:
1. Fish Culture – the human effort of raising the maximum productivity of
fish and other fishery aquatic products and maintaining the supply of
these products to satisfy human needs.
2. Fish Capture – branch of fishery science deals with the scientific
method of catching fish as well and the type of fishing gear used.
3. Fish Preservation – branch of fishery science that deals with the
scientific method of preserving fish and other fishery aquatic products to
prevent spoilage.

211
BRANCHES OF FISHERY ARTS OVERVIEW
Fish Culture
Fish culture is an art and science of raising, rearing and propagating of
fish and other aquatic products under controlled or semi-controlled
environment. It is primarily practice for the support and sustenance to human
needs for consumption.
Fish culture under controlled condition is one undertaken in an
aquarium, tank, hapa, fish cage, pen or pond.
Fish culture has three major phases: fish propagation, fish cultivation
and fish conservation.
Fish Propagation is defined as the natural or artificial method of
promoting or enhancing reproduction and survival of fish and other aquatic
products. It includes keeping, maintaining and spawning breeders in tanks or
ponds, hatching the eggs in hatchery facilities, and nursing the delicate larvae
up to size suitable for stocking in the grow-our or rearing areas.

212
Natural Method
Artificial Method

213
Fish Cultivation simply means the rearing of fish and other aquatic
products from very young stage like fry and fingerlings, to marketable size. It
is done in fresh, brackish and marine waters in any of the rearing contraptions
or structures. The other types of sub-classification based on the techniques
applied and financial investments, namely: extensive, semi-intensive and
intensive.
 Extensive Fish Farming
The fish feed entirely from the food web within the pond, which
may be enhanced by the addition of the fertilizer or manure.
 Semi-Intensive Fish Farming

214
The fish still obtain significant nutrition from the food web
within their pond, but they are also given supplementary feed.
 Intensive Fish Farming
The fish are kept at too high a stocking density to obtain
significant amount of feed from their environment.
Fish Conservation is the public control and various maintenances of the
various fisheries where fish and other fishery products are deprived. It work
should be designed to insure maximum sustainable yield of fish. For instance,
the continuous use of fishpond without proper maintenance, like applying
fertilizer, lowers the productivity of the soil. It lessens the capacity of fish to
reproduce.

215
Fish Capture
Fish Capture is a rule or principle of capturing or operating methods of
fish and carried out distinct means with some regularity. It includes the fishing
gears, technologies and equipments for systematic capturing.
Fish Preservation
It is any operation that can prevent or inhibit the natural process of
breakdown or decomposition taking place in the fish. It is known as fish
processing.

LESSON 4:
MORPHOLOGY OF COMMON FISH – ITS PARTS AND
FUNCTIONS
External Parts of the Fish and Their Functions
1. Operculum/gill cover - part of the fish that covers the gills
2. Scales - part of the fish that cover the body

218
3. Lateral lines - lines along the body of the fish used
to help the fish adapt itself to its new
environment
4. Fins - part of the fish that used for
swimming, balancing and propelling
in water
5. Eyes - part of the fish that used for seeing
6. Mouth - part of the fish that used for
swallowing objects, particularly food
7. Anus - part of the fish that serves as an
excretory organ of the fish where the
waste matter coming from the body of
fish passes out
8. Caudal Peduncle - part of the fish that connect the body
and the tail
9. Nostril - part of the fish that used for smelling
10.Vent - the opening between the anus and the
anal fin where the fish will excrete
either eggs or sperm. Also known as
genital papilla

219
Internal Parts of Fish and their Functions
1. Spine - the primary structural framework
upon which the fish’s body is built.
It connects to the skull at the front of
the fish and the tail at the rear. The
spine is made up of numerous
vertebrae, which are hollow and
which protect the delicate spinal
cord
2. Spinal cord - the part that connects the brain to the
rest of the body and relays sensory
information from the body to the
brain, as well as instruction from the
brain to the rest of the body
3. Brain - the control center of the fish where
both automatic functions and higher
behaviours occur. All sensory
information is processed here

220
4. Lateral line - one of the fish’s primary sense
organs. It detects underwater
vibration and is capable of
determining the direction of their
source
5. Swim or Air Bladder - a hollow, gas-filled balance
organ that allows a fish to conserve
energy by maintaining neutral
buoyancy in water
6. Kidney - filters liquid waste materials from
the blood. These waste are then
passed out the body
7. Stomach and intestines - break down food and absorb
nutrients
8. Pyloric caeca - finger like projection located near
the functions of the stomach and the
Intestine. It known to secrete enzymes
that aid digestion. It may also
function to absorb digested food or do
both
9. Liver - it assists digestion by secreting
enzymes that break down fats, and
also serves as storage area for fats and
carbohydrates.
10.Heart - circulates blood throughout the body

221
11.Muscle - provide movement and locomotion.
These are parts of the fish that are
usually eaten. They compose the fillet
of the fish
12.Gonad - hormone-secreting sexual gland of a
fish.
Fish Scales Tell the Age of a Fish
Look at the image of the fish scale. Like a tree, scales show rings that
indicate periods of growth. Rings that are farther apart occur when the fish
grows well and there is a lot of food in the summer season. Rings that are close
together occur when the fish does not get much food and grows slowly. On the
scale you can identify the summer growth and the winter growth. (There will
be several rings in each).
The core represents the fish when it was first born, as a fry. The rings
near the edge are the most recent periods of growth.

222
Types of Fish Scales
Placoid - It resembles a miniature tooth called denticles. Ex. shark scales
Cycloid - It is oval or circular in outline and has a smooth and exposed
rear edge.

223
Ctenoid – It is scales that have a rear edges made of small brush-like
spines or comb liked teeth. Ex. Scales of perch, pongies and bass
Ganoid – It is a four- sided plate that fits closely against adjacent plates
without overlapping.
Parts of Gills
Diagrammic Representation of Two Forms of Fish Gills
1. Gills Filaments - used for exchange of gases such as
oxygen and carbon dioxide
2. Gills Arch - used for support and passing for
blood to and the gill filaments
3. Gill Rakers - used for straining food from the water

LESSON 1:
ASPECTS, CLASSIFICATIONS AND METHODS
OF FISH CULTURE
Many programs and activities had been done in response to the
problems regarding the shortage of the supply of fish in the country. One of
which these program is Fish Culture. Fish culture then must be introduced to
enhance awareness and adopt some of the technology and its adoption as
additional source of food and income.
Nature and Scope of Fish Culture
It is the rearing of fish from fry to marketable size. It also cultivates
other aquatic products such as crabs, prawns and shrimps. Fish cultivation is
undertaken in fresh, brackish and marine waters based from the environment
and water supply.
The fresh water type of fish cultivation is carried out in lakes, rivers,
dams or reservoirs and marshes. Structures used for this type are fish ponds,
fish pens, fish cage, fish tank and raceways. The species of fish that are usually
raised are tilapia, carp, catfish, mudfish and milkfish.

232
The brackish water type of fish cultivation is carried out in tidal flats or
along margins of estuarine areas. The structures as those in freshwater are used
in this type is the same, except the raceways. The major species of fish
cultivated are tilapia, milkfish, shrimps and crabs. Fish pond is the predominant
type of fish cultivation in the country. It contributes utmost production of
inland waters. Milkfish is the number one product.
The marine water type of fish cultivation is carried out in salt waters or
open ocean waters. The farms are positioned in deeper and less sheltered
waters, where currents are stronger than they are inshore. The structures used
for this type are fish cage, fish tank, fish pond and raceways. The species of
fish that are shellfish like prawns, or oysters and seaweed.
Phases or Aspects of Fish Culture:
1. Fish Cultivation
The rearing of fish under controlled and semi-controlled condition.

233
2. Fish Propagation
The process of increasing fish life either by natural or artificial means of
reproduction.
3. Fish Conservation
The scientific means of conserving fish and other fishery aquatic

234
products/resources. It helps to keep the sport of fishing alive. Also, helps to
maintain the balance of certain ecosystems. Fish are important to the planet
and fish conservation can help maintain nature’s balance.

b. brackish-water species
c. marine or saltwater species
Methods of Fish Culture
Based on the structures used in fish cultivation, they can be classified
into five methods. These are the fish pond, fish pen, fish cage, fish tank and
open-water method.
Fish pond is the most widely used. Fry or fingerlings of one or more
species are stocked and reared in pond up to harvest time. Natural food is
grown in pond. The supplementary feed is added. The method of harvesting is
draining the pond. Retrieval of fish in this way is complete. Another method of
harvesting is freshening in case of bangus. Having positive rheotaxism, the fish
are induced to go against water current by the gate and concentrated into a
catching pond where they are scooped.
The fish pen method of fish cultivation is undertaken in net enclosures
in shallow protected areas of inland waters. Bamboo and wood materials ate
used as post and braces. Its lower end is embedded in the mud to prevent
escape of stock by excavating under, while the upper end is extended two
meters or more beyond the water level to escape of fish by jumping out.
Harvest of fish is done by seining or shocking them with electricity.
The fish cage method of fish cultivation is also undertaken in inland
bodies of water, both in flowing and still water ones. The structure used is also
made of nets. PVC pipes as framing materials is preferred to that of wood or
bamboo. A cage is much smaller than a fish pen. The cage is closed on all sides

236
and installed in suspension. Fish cage is stationary and movable. Floating and
fixed cages have open top. Growth rate of fish is dependent on the kind and
amount of food given and suitability of the environment. Harvesting of stock is
relatively easy and complete. The fish is either scooped or the cage is merely
brought out of the water to empty the fish.
The fish tank method of fish cultivation is practiced primarily by fish
hobbyists and in pet shops. The method employs varying sizes and shapes of
fish culture structures. These include glass bowls or aquaria and wooden or
concrete tanks. This method cultivation is done outdoor and indoor. The
method involves rearing or breeding of ornamental or fancy, colourful species
of fish.
A fifth method of fish cultivation is open-water method. It is done in
bays, coastal lagoons, canals and similar environments.

In every area of specialization, there are terminologies used to give a
specific meaning for a matter. This will served as a common idea to the
professionals in their respective fields. So as is in this area, there are scientific
terminologies. In this lesson, it will tackle about various common terminologies
used in fish culture.

FISH CULTURE FACILITIES
Many facilities that can operate in fish culture. In this lesson, we only
tackle the common and frequently used facilities. They are Fish Pond, Fish
Cage, Fish Pen, Fish Tank, Hapa and Raceway. All of them will be discussed
below.
1. FISH POND
According to the www.agriculturenigeria.com that fish pond is a
confined body of water where fish are raised under controlled
conditions. Fish can also be raised in plastics, fiber stars and wooden
rafts. There are three main types of ponds in construction. This either be
earthen pond, concrete pond and riprap.

where fish are reared from fry up to pre-
fingerling size.
2. Transition pond - is a compartment where fish are reared from
pre-fingerling size to post fingerling size
before stocking compartments, it is also
known as stunting pond.
3. Rearing pond - is the largest compartment of a fishpond
where fishes are reared from post fingerlings

LESSON 4:
CULTIVABLE FISH AND CRUSTACEAN SPECIES
There are vast species of aquatic animals with their unique
characteristics around the globe in freshwaters, brackish waters and saltwater
yet not all of them are edible to consume by human for food because of health
issues if eaten and the threat of extinction to their race which are protected by
local governments. So, there are only specific species of fish for food and
legally to produce and commerce. In this lesson, it will discuss about the
Philippine common species of cultivable fish and crustaceans in fish facilities,
their characteristics and natural food according to their water habitats.

256
Common Cultivable Fish Species:
Nile Tilapia (Oreochromis niloticus) is a tropical species that prefers
to live in shallow water. The lower and upper lethal temperatures for Nile
Tilapia are 12˚C and 42˚C, respectively, while the preferred temperature ranges
from 31˚C to 36˚C. It is an omnivorous grazer that feeds on phytoplankton,
periphyton aquatic plants, small invertebrates, benthic fauna, dentitus and
bacterial films associated with detritus. Nile Tilapia can live longer than 10
years and reach an exceeding weight of 5 kg.
Mozambique Tilapia (Oreochromis mossambicus) is a freshwater and
brackish water inhabitant. It lives in warm, weedy pools of sluggish stream,
canals and ponds. Is mainly diurnal, occurs at temoeratures ranging from 8˚C to
42˚C. Omnivorous, feeds on almost anything from algae to insects but also
crustaceans and fishes. Mozambique Tilapia reaches a maximum size to 36 cm.

257
Common Carp (Cyprinus carpio) is live in the middle and lower
streams of rivers, in inundated areas, and shallow confined waters such as lakes
and water reservoirs. Carps are mainly bottom dwellers but search for food in
the middle and upper layers of water body. Best growth is obtained when water
temperature ranges between 23˚C and 30˚C. The fish can survive cold winter
periods. It is omnivorous, with a high tendency towards the consumption of
animal food such as water insects, larvae of insects, worms, molluscs, and
zooplanktons. Common carps can reach 0.6 to 1 kg body weight within one
season in the polycultural fish ponds of tropical and subtropical areas.
Bighead Carp (Hypopthalmichthys nobilis) is a eurythermic fish,
being to tolerate water temperatures of 0.5˚C to 38˚C. It inhabits lakes, rivers
and reservoirs. Bighead carp normally dwell in the upper layer of the water
column and prefers high fertility water with abundant natural food. Basically, it
is a zooplankton eater throughout its life under natural conditions yet also

258
consumes artificial feed in culture ponds. Bighead Carp are fast growing and
become very large in size reaching a maximum weight of 40 kg.
Philippine Catfish (Clarias batrachus) is an air breathing fish inhabit
in lowland streams, swamps, ponds, ditches, rice paddies and pools left in low
spots after flood. It can walk and leave the water to migrate to another water
bodies using its auxiliary breathing organs. It usually confined to stagnant,
muddy water and tolerates temperature from 10˚C to 28˚C. Omnivorous that
feed on insect larvae, earthworms, shell, shrimps, small fishes, aquatic plants
and debris. Approximately, its maximum length is 47 cm and maximum weight
of 1.2 kg.
Bighead Catfish (Clarias macrocephalus) is an air breathing fish lives
in lowland wetland and rivers. Occurs in shallow, open water and is capable of
lying buried mud for lengthy period in the time of ponds and lakes evaporate
during dry seasons. It can also extend its fins to move out of the water. Found
in medium to large-sized rivers, stagnant water bodies including sluggish

259
flowing canals and flooded fields. It can tolerate temperatures from 10˚C to
28˚. Omnivorous that feed on aquatic insect, young shrimps, small fishes and
aquatic plants. Its maximum length is 120 cm and maximum weight is 45 kg.
North African Catfish (Clarias gariepinus) is found in lakes, streams,
rivers, swamps and floodplains, many of which are subject to seasonal drying.
The most common habitats are floodplain swamps and pools where they can
survive during the dry season(s) due to their accessory air breathing organs. It
undertake lateral migrations from the larger water bodies, in which they feed
on aquatic insects, worms, gastropods, small crustaceans, small fishes, aquatic
plants, terrestrial seeds and berries, small birds and small mammal as being an
omnivorous. It can live in the temperature of 10˚C to 28˚C. The record
individual from Country of Malawi was 16.1 in kg and the max length is 150
cm.
Snakehead Murrel (Channa striata) is a ray-finned fish that perch-

260
like in form and its head is like of a snake. It is a fresh and brackish water
inhabitant such as ponds, streams, rivers, stagnant and muddy plains. Found
mainly in swamps but also occurs in lowland rivers. It can survive in dry
season by burrowing in bottom mud of lakes, canals and swamps as long as
skin and breathing apparatus remain moist and subsists on the stored fat. Feed
on fish, frogs, snakes, insects, earthworms, tadpoles and small crustaceans as
being a carnivore. Snakehead murrel can live in temperature of 23˚C to 27˚C.
Its maximum length is 100cm and weight of 3kg.
Giant Gourami (Osphronemus gouramy) is a laterally compressed
(compressiform) fish. It has the ability to breath air through a specific organ
called labyrinth (a much-folded suprabranchial accessory breathing organ),
which appears in juviniles about 30 days after hatching and become functional
around 40 days. This fish is omnivorous but with a strong vegetarian tendency,
it can ingest various aquatic and terrestrial plants, although it can also eat a
wide range of other food resources such as frogs, tadpoles, snails, small fishes
and other small aquatic animals. Giant gourami prefers calm fresh waters
especially slow-moving areas such as lakes and large rivers. They are also
found in flood plains and irrigation canals. It lives in tropical temperature of
water. It can reach a remarkable size but normally the maximum size is 45-50
cm. Growth rate is quite slow and may reach commercial size of 500 to 750 g
within 9-14 months of growout. To achieve larger sizes 1 to 2 kg, an extended

261
period of growout rearing is required, generally compromising 25 to 35 months
in total.
Barramundi (Lates calcarifer) is also known as seabass, it inhabit
freshwater, brackish water and marine habitats including streams, lakes,
billabongs, estuaries and coastal waters. Barramundi are opportunistic
predators; crustaceans and fish predominate in the diet of adults. It is highly
fecund; a single female (120 cm) may produce 30-40 million eggs.
Consequently, only small numbers of broodstock are necessary to provide
adequate numbers of larvae for large-scale hatchery production. Larvae recruit
into estuarine nursery swamps where they remain for several months before
they move out into the freshwater reaches of coastal rivers and creeks
considering them as a diadromous fish. They usually occur at a temperature
range of 26˚C to 29˚C and between 10 to 40 m deep. Its size is commonly
between at 25 to 100 cm.

262
Orange-spotted Grouper (Epinephelus coioides) has body elongated,
not very compressed, light greyish brown dorsally, shading to whitish on side
and ventrally, with numerous brownish orange or brownish yellow spots on the
size of pupil or smaller on head and body. It inhabits turbid coastal reefs and is
often found in brackish water over mud and rubble. Juveniles are common in
the shallow waters of estuaries over sand, mud, gravels and among mangroves.
It feeds on small fishes, shrimp and crabs. It is generally cultured in floating net
cages or earthen pond, but cage culture is more common in Southeast Asia.
Most of the brooders are collected from wild and reared for 1 to 7 years using
seawater at a constant temperature of 27˚C to 28˚C. The fish are fed with
frozen sardines, mackerels, cuttlefish, squids and top-shell clams because these
foods have high contents of cholesterol, phospholipids and polyunsaturated
fatty acids.

263
Malabar Grouper (Epinephelus malabaricus) is a ray-finned fish and
has perch-like body. It has light grey to yellowish brown color; five slightly
oblique dark brown bars that bifurcate ventrally; numerous small black spots
and blotches in head and body. It inhabits in marine, brackish, reef-associated
waters such as coral and rocky reefs, tide pools, estuaries, mangrove swamps
and sandy or mud bottom from shore to depths of 150 m. It feed primarily on
fishes and crustaceans. Malabar grouper can tolerate water temperature from
26˚C to 29˚C. Its common maximum length is 234 cm and maximum weight of
150 kg.
Orange-spotted Spinefoot (Siganus guttatus) is also known as rabbit
fish by the similarity of the nose. It is a ray-finned fish with perch-like body. It
has a bright yellow spot adjacent to last few rays of dorsal fin, head with lines
and spots. Its spine is stout, pungent and venomous. Inhabits in marine and
brackish water to include turbid inshore reefs among mangroves; tolerates or
even prefers low salinities. Fry settlers in seagrass beds around river mouths
and adults enter and leave rivers with tides but also found on drop-offs of
inshore fringing reefs down to 6 m. It feeds on benthic algae. Unlike other
siganids, this species is reported to be active at night as being a nocturnal fish.
It can tolerate water temperature from 24˚C to 28˚C. Its common maximum
length is 42 cm.

264
Vermiculated Spinefoot (Siganus vermiculatus) is is also known as
rabbit fish by the similarity of the nose. It is a ray-finned fish with perch-like
bluish white body, head brown to brownish or golden yellow with irregular
lines. Its spine is stout, blunt or pungent and venomous. It inhabits in marine
and brackish water, juveniles live among mangroves then move out to lagoon
and coastal reefs as they mature. It feeds on algae growing on seagrass,
mangrove roots and rocks. Adult congregate inshore in groups of several
hundreds to spawn in summer. Adults on coastal reefs are subject to strong
currents. The species has a high fecundity of 350,000 per spawning season. It
can tolerate water temperature from 19˚C to 38˚C. Its common maximum
length is 45 cm.
Spotted Scat (Scatophagus argus) is a ray-finned fish with perch-like
quadrangular body shape. Juveniles with a few large roundish blotches, about
size of eye, dorsal head profile is steep. Eye moderately large and snout is

265
rounded. It inhabits in fresh, brackish and marine waters such as harbors,
natural embayments, brackish estuaries and lower reaches of freshwater
streams, frequently occurring among mangroves. It feeds on worms,
crustaceans, insects and plant matters. The dorsal, anal and pelvic spines are
believed by Philippine fishers to be venomous and capable of inflicting
wounds. It can live in the water temperature from 20˚C to 28˚C and usually its
maximum length is 38 cm.
Milkfish (Chanos chanos) is a fusiform, elongated, moderately
compressed, and smooth streamline body fish. It has body color silvery on
belly and sides grading olive-green or blue on back, transparent tissue covers
eye. It is the only species in the Family Chanidae. Its distribution is restricted to
either low latitude tropics or the subtropical northern hemisphere along
continental shelves and around islands, where temperatures are greater than
20˚C. Milkfish only spawn in saline waters. Spawning takes place near coral
reefs during the warm month of the year. Juveniles and adults eat a wide
variety of relative soft and small food items, from microbial mats to detritus,
epiphytes and zooplankton. It attains typical length of 1m but may reach
maximum length of 1.8m.

266
Common Cultivable Prawn/Shrimp Species:
Giant Tiger Prawn (Penaeus monodon) is similar to all penaeid
shrimp, the rostrum well developed and toothed dorsally and ventrally. Its
carapace has without longitudinal or transverse sutures. Depending on
substratum, fees and water turbidity, body colors vary from green, brown, red,
grey, blue and transverse band colors on abdomen and carapace are alternated
between blue or black and yellow. Penaeus monodon was originally harvested
together with other shrimp species from traditional trapping-growing ponds or
as a significant by-product of extensive milkfish ponds. It is mature and breeds
only in tropical marine habitats and spends their larval, juvenile, adolescent and
sub-adult stages in coastal estuaries, lagoons or mangrove areas. In the wild,
they show marked nocturnal activity, burrowing into bottom substratum during
day and emerging at night to search for food as benthic feeder. Under natural
conditions, the giant tiger prawn is more of a predator than an omnivorous
scavenger or detritus feeder than other penaeid shrimp. Adults are often found
over muddy sand or sandy bottoms at 20 to 50 m depth in offshore waters. The
females are highly fecund with gravid females producing as many as 500,000
to 750,000 eggs. Hatching occurs 12 to 15 hours after fertilization. It feeds on
benthic detritus, polychaete worms and small crustaceans. Healthy adult
females can grow 25 to 30cm and weighted of 200 to 320g while healthy adult
males can grow 20 to 25cm and weighted of 100 to 170g.

267
Indian White Prawn (Penaeus indicus) is similar to all penaeid
shrimp, carapace rather smooth, lacking gastro frontal and hepatic crest, ad
rostral crest extending as far as or just before epigastric tooth, rostrum slightly
curve at tip and sigmoidal-shaped, usually bearing 7 to 9 upper teeth (including
those on carapace) and 3 to 6 lower teeth, rostral crest generally slightly
elevated in large specimen including adult females. Its body color is semi-
translucent, somewhat yellowish white (small specimens) or greyish green and
covered with numerous minute dark brown dots, eyes light brown mesh-like
stripes, rostral and abdominal dorsal crests reddish brown to dark brown. The
methods of brackish water aquaculture are applied whether in cultures practices
followed such as traditional, extensive, modified extensive, semi-intensive or
intensive. It inhabits the coast of East and South Africa, Southwest and East
coast of India, Bangladesh, Thailand, Malaysia, Philippines, Indonesia,
Southern China and Northern coast of Australia. Penaeus indicus is non-
burrowing, active both day and night, and prefers a sandy mud bottom. Adults
are normally found at depths less than 30m but have also been caught from
90m. The shrimp mature and breed mostly in marine habitats and spend the
juvenile and sub-adult stages of 30 to 120 mm total in length (TL) in coastal
estuaries, backwaters or lagoons. Juveniles can tolerate a much wider range of
salinity (5-40%) than asults. On the southwest coast of India the juveniles
support a good commercial fishery in the backwaters and paddy fields. It is also
highly fecund, ranging from 68,000 to 1,254,200 eggs from females of 140-
200mm TL. Depending upon the temperature, hatching takes place within 8-12

268
hours after spawning. The postlarvae migrate into the estuaries, settle and feed
on benthic detritus, polychaete worms and small crustaceans, and remain there
until they attain 110-120 mm TL. These sub-adults then return to the sea and
get recruited into the fishery. The size of Penaeus indicus used for broodstock
development should preferably be above 145mm TL (20g) for females and
140mm (17g) for males.
Banana Prawn (Fenneropenaeus merguinsis) is widely distributed in
the Indo-West Pacific region in both tropical and subtropical waters. To include
from Persian Gulf to Thailand, Hong Kong, the Philippines, Indonesia, New
Guinea, New Caledonia and North Australia. It inhabits in the bottom mud,
estuarine and marine about 10 to 45 m in depths. Its usually maximum total
length is 240 mm (female). It has been cultured in extensive ponds with natural
seeding for a long time in Asia and recently in semi-intensive and intensive
ponds. Supplementary feeding occurred only later in improved extensive
farming, with usually stocked with wild caught or hatchery-produced
postlarvae. Although F. merguinsis does not grow as fast as P. monodon, their
ability to mature and spawn in captivity and their short life cycle ensure a
consistent production of postlarvae and a great opportunity to domesticate the
species. This would eliminate the reliance of the prawn farming industry on
wild broodstock and more importantly, allows the development of fast growing
or pathogen-free stocks through selective breeding. Such low cost of
broodstock, ease in larvae rearing and potentially low feed cost.

269
Greasyback Prawn (Metapenaeus ensis) is commonly called mud
prawn, sand prawn in catering trade. It is popular due to its rich-tasting
nutritious flesh. Cahracteristics of M. ensis include a wide distribution, strong
adaptability, omnivorous feeding habit, fast growth and high commercial value.
It breeds in seawater or brackish water but it can also be bred in freshwater
after domestication. After 100 days in cultivation with a favourable
environment and abundant food, juveniles will grow into adult commercial
shrimps of 10cm in length.
Giant Freshwater Prawn (Macrobrachium rosenbergii) is the largest
Macrobrachium species. The maximum recorded size for males and females
are 33cm and 29cm in length. Mature male prawns are larger than females. The
head of the male is also proportionately larger and the abdomen is narrower. M.
rosenbergii is nocturnal, bottom dwelling and sluggish in nature and is
territorial. During the day they remain half buried in sediments and prefers

270
shallow, detritus rich and vegetated areas. In temperature regions, the breeding
season is summer while in tropical regions it is to the onset of the rainy season.
Its spawning occurs two or more times per season.
Common Cultivable Crab Species:
Swamp Crab (Scylla serrata) is a crab with smooth carapace and
strong transversal ridges. Its gastric zone is on the carapace with deep H-
shaped groove. Front with 4 broad lobes, all more or less in line with each
other, 9 broad teeth on each anterolateral margin, all of them with similar size
and projecting obliquely outwards. It has a strong chelipeds with well
developed spines on the outer surface of carpus and on the anterior and
posterior dorsal parts of propodus. Its carapace color is green to almost black
with legs that may be marbled. The three other Scylla species prefer less saline
water. Farming of this species has developed from low density pond
polyculture with fish and shrimp, using wild seeds introduces tidally or
intentionally, to monoculture in ponds and pens. Typically associated with
mangroves in estuaries and sheltered coastal habitats, they are found in soft
muddy bottoms where they dig deep burrows. Their courtship and mating occur
in estuaries. Mature S. serrate migrates offshore (up to 50km) to spawn. They
may spawn at any time during the year. The number of eggs produces may
range from 1 to 6 million in a single spawning with at least 3 batches. Males

271
can grow up to 3kg with 28cm carapace width. Mature females have wide and
dark abdomens and dark orange ovaries that fill the cavity under the carapace.
Mud Crab (Scylla paramamosain) is a crab with a carapace usually
green to light green, plam green to greenish blue with lower surface and base of
fingers usually pale yellow to yellowish orange. Its carapace common width is
between 15 and 18cm. Inhabits rock areas, near reef and mangroves. Members
of the order Decapoda are mostly gonochronic. Mating behaviour:
Precopulatory courtship ritual is common (through olfactory and tactile cues);
usually indirect sperm transfer. Its recorded maximum carapace length is 20cm.
Common Cultivable Lobster Species:
Ornate Spiny Lobster (Panulirus ornatus) is a lobster under the
family of Palinuridae. It has maximum total body length of 50cm but usually
much smaller (30 to 35cm). It is found in shallow, sometimes slightly turbid

272
coastal waters from 1 to 8m depth, with a record of 50m deep. It inhabits sandy
and muddy substrates, sometimes on rocky bottom, often near the mouth of
rivers but also on coral reefs. Juveniles occur in holes and crevices which are
partially covered by seagrass or macroalgae. It is solitary, may live in pairs and
has been found in larger concentrations. It is an omnivore species. Members of
the order Decapoda are mostly gonochronic. Mating behaviour: Precopulatory
courtship ritual is common (through olfactory and tactile cues); it is also
indirect sperm transfer. It can found in the Indo-West Pacific region.
Common Cultivable Mollusk Species:
Slipper Cupped Oyster (Crassostrea iredalei) is a shell medium sized,
very variable in shape but generally higher than long, roughly rounded, oblique
triangular or elongate ovate in outline. It’s left (lover) valve rather thick but
light weighted, more convex and larger than right (upper) valve. The color of
outside shell is dirty white, often flushed with pale greyish brown. The right
valve is frequently with a few darker purplish grey radial bands in early stages
of growth. The interior of valves are whitish and shiny, often with irregular
areas of chalky white, deep puple-brown on posterior adductor scar. Its
geographical distribution is restricted to the Philippine Archipelago and
Malaysia. C. iredalei attached to hard objects or growing in bunches, on
various soft bottoms, especially in bays and estuaries with somewhat reduced
salinity, intertidal and shallow subtidal water, and suspension-feeding. This
brackish water species is noted for its tasty creamy flesh and its culture

273
required a salinity range of 15 to 25ppt. Its recorded maximum shell height is
15cm and commonly 8cm in length.
Donkey’s Ear Abalone (Haliotis asinina) is actively collected in the
Southeast Asian countries for its shell and large fleshy animal. It is common
but not aggregating in dense populations. The depth where they are usually
found is at 0 to 10m. In life, the exceptionally large green mantle almost covers
the shell which is them devoid of encrusting marine growths, unlike of the
other species. It is active at night, feeds on epilithic algae by grazing. Found in
intertidal, on coral reefs. H. asinine is mostly gonochronic and broadcast
spawners. Life cycle: Embryos develop into planktonic trocophore larvae and
later into juvenile veligers before becoming fully grown adults. Its recorded
maximum length is 12cm and its common size is 9cm.
Green Mussel (Perna viridis) is an economically important mussel, a
bivalve belonging to the family of Mytilidae. It is harvested in the wild and

274
grown in aquaculture facilities in its native area. The shell tapers to a sharp,
downturned beak and has a smooth surface covered with a periostracum. The
ventral margin of the shell is straight or weakly concave. The ridge which
supports the ligament connecting the two shell valves is finely pitted. The beak
has interlocking teeth; one in the right valve and two in the left. The wavy
posterior end of the paleal line and the large kidney-shaped adductor muscle
are diagnostic features of this species. Periostracum can be vivid green to dark
brownish-green near the outer edge and olive-green near the attachment point.
The interior of the shell valves is shiny and pale bluish green. It can usually
found up to 10m depth and forms dense population (up to 35,000 individuals
per square meter). This species in an efficient filter feeder, feeding on small
zooplankton, phytoplankton and other suspended fine organic material. Sexes
are separate and fertilisation is external. Spawning generally occurs twice a
year between early spring and late autumn, however, in the Philippines and
Malaysia spawning occurs year round. Sexual maturity occurs at 15 to 30mm
shell length. Life span is about 3 years. It is found in estuarine habitats with
salinities ranging from 18 to 33 ppt and temperatures from 11˚C to 32˚C. It can
reach 150mm.
Common Enemies of Fish and Crustacean
1. Predator - fish and other animals that prey on the cultured
species of fish and crustacean
2. Competitors - fish and other animals that compete with the
cultured species in terms of food, space and oxygen
3. Nuisances - crustaceans and other animals that do a lot of
damage to the food and in the habitat of fish

275
Characteristics of Fish and Crustacean that are Suitable for Pond Culture
1. Fish should be palatable and good tasting – the fish must have a
delicate flavour.
2. Fish must be a fast grower – the fish must be able to grow rapidly or
can give a possibility of four or more harvests a year.
3. Fish should be resistant to pests, diseases and parasites – the fish
should not succumb to abrupt changes in temperature or salinity and
can tolerate such conditions in all its existence.
4. Fish should be a universal feeder – the culture fish require food
which can be grown easily and abundantly under favourable
conditions.

LESSON 2:
FISH PRESERVATION PRINCIPLES
AND AGENTS OF SPOILAGE
Principles of Fish Preservation
1. Prevent or delay microbial decomposition of fish
2. Prevent or delay self-decomposition.
3. Prevent other causes of spoilage of fish like physical damage
Changes in Fish After Death
1. Changes in Appearance are the color starts to fade until it becomes
dull as spoilage progresses.
2. Rigor mortis is characterized by the stiffening of the muscle tissue.
This state lasts only for a few minutes in some fish to several hours in others.
The fish in this state is considered fresh.

355
3. Autolysis is the breakdown of tissues caused by enzymes. Since it
softens the tissue, it proves the activity of microorganisms.
4. Putrefaction is the state when the components of the flesh are
assimilable forms. It is accompanied by a foul odor, which is the result of the
breakdown of protein. The fish at this stage is spoiled and undesirable.

357
Agents of Spoilage
1. Microorganisms
Three Main Groups of Microorganism
a. Bacteria - responsible in the breakdown of plant and animal material
and the possible the return of simple inorganic compounds to the soil. The
result of this breakdown is spoilage, fermentation and decay. Since fish is an
organic matter, it spoils easily. As soon as it dies, bacteria act on it.
b. Molds - fuzzy or cottony organisms that grow on the surface of the
food. They are responsible for the white, orange, black, green or blue green
colonies on the surface of the food.

358
c. Yeasts - whitish to yellowish colonies on the surface of the food. They
appear as a film on the surface of the liquid or as sediments at the bottom.
2. Enzymes - proteins that act as biochemical catalysts in living
organisms. They are normally present along the digestive tract and help in the
breakdown of food into assimilable forms.

359
Classification of Bacteria According to Shape
1. Coccus - round
2. Bacillus - rod-shaped
3. Spirillus - spiral
4. Staphylococcus - grapelike
5. Streptococcus - chainlike
Classification of Bacteria According to Their Temperature Requirement
1. Thermophilic - thrive at high temperature (heat loving)
2. Psychrophilic - thrive best at low temperature
(cold-loving organisms)
3. Mesophilic - those that thrive between low and high
temperatures
Classification of Bacteria According to Their Oxygen Requirement
1. Aerobic - requires free oxygen in order to live
2. Anaerobic - lives in the absence of free oxygen
3. Facultative - grows with or without free oxygen
Types of Enzymes
1. Lipolytic - enzyme that acts on fats
2. Proteolytic - enzyme that acts on proteins
3. Amylolitic - enzyme that acts on carbohydrates

LESSON 3:
METHODS, TOOLS AND EQUIPMENTS
METHODS OF FISH PRESERVATION
1. Fish Curing
It includes all the methods of fish preservation except refrigeration and
canning. It is the process of preservation by the use of preservatives and other
chemicals for the purpose of keeping fish and other fishery products fresh for
future use.
Types of Fish Curing

362
A. Salting is the application of salt to product. It is considered the basis
of all methods of fish preservation
Salt is the colorless or white crystalline compound known chemically as
sodium chloride (NaCl) occurring abundantly in nature, both in solid form and
in solution.
Factors Affecting Salting
a. Composition of Salt

363
 Pure Salt is the better quality salt. It is soft and flabby and has
yellowish white color.
 Impure Salt is firm and rusty in color.
b. Temperature
Its condition makes the certain object require enough quantity
and quality of efforts to produce the favourable state. High temperature makes
salt dissolve faster, permitting a rapid penetration of the product with salt.
c. Methods of Salting
 Kench Salting
 Dry Salting to Make Brine
 Brine Salting
 Fermenting
d. Methods of Cleaning
 Whole Fish
 Splitted Fish
 Gutted Fish

364
e. Size of the Fish
It defines how required salt is needed and depends on how the
speed of salting occurs. The small sized of fish is salted faster than larger size
of fish
f. Storage of Fish
B. Drying and Dehydration is the lowering of water content of the
product to a degree where bacteria cannot grow and reproduce with the aid of
heat.
 Drying known as natural drying used
 Dehydration is of chemical devices to provide artificial heat for
drying

365
Factors Affecting Drying
a. Humidity of air
b. Velocity of the wind
c. Intensity of the sunshine
 Humidity – amount of moisture in air
 Velocity – speed of air/wind
Factors Affecting Dehydration
a. Kind of drier used
b. Temperature range
c. Storage of finished product
d. Relative humidity
The finished products of drying and dehydration are commonly called
daing or tuyo.
C. Smoking is a method of preserving fish by the application of smoke
and other interrelated processes such as salting, drying and heat treatment.

366
Smokehouse - an airtight container where smoke can be introduced
Types of Smoking
 Hot Smoking or barbecuing - a slow type of broiling that places the
product in close proximity to the fire. The food is cooked and smoked in
temperature ranging 150◦F to 190◦F.
 Cold smoking - method of smoking in which the fish are hung at some
distance from a low smouldering fire and cured at temperatures ranging
from 90◦F to 110◦F.
Factors Affecting Smoking
 Kind of Fish - fat fish are preferable to lean ones. Scaly fish are usually
used to obtain an attractive appearance of the finished product
 Condition of raw materials
 Kind of smoke-producing materials
a. Hard wood - good quality of smoke is produced
b. Soft wood - thin smoke is produced; thus, a low grade of
smoked product
 Length of smoke curing

367
C. Pickling is the preservation of food by the use of vinegar and other
spices. Pickling of fish as a method of preservation is not commercially done in
the Philippines because the preservative action of vinegar is short. Pickling has
some digestive action in fish which renders it softer and pastier. Pickled fish is
usually used as appetizer so preservation by this method is recommended for
use at home.
2. Canning or Bottling is the application of heat to food in a hermetically
sealed container at a temperature and for a period of time
sufficient to destroy microorganisms and to render any
bacterial cell for a definite period of time.

368
Basic Canning Equipment
 Can sealer is a machine or instrument that is used to close the open ends
of tin cans.
 Pressure cooker is a modern household device used for processing food
for a definite period of time and pressure.

369
 Tin cans and glass jars are containers locally available for canning
purposes only.
 Measuring spoons & cups are devices used to measure liquids and solids
ingredients.

370
 Colander is a receptacle for draining purposes.
 Basins are containers used for washing and for the preparation of brine.

371
 Thermometer is a device used to check temperatures of cooking, drying
and cold storage.
 A clock is an instrument used to determine the length of processing,
salting, steaming or frying

372
 Knives are tools used in cleaning, cutting fish into accurate sizes
 Cutting board is a durable board used primarily as guide so that exact
sizes of fish will fit into the different containers.
