This lesson plan outlines a horticulture class for grade 7 students on different designs of irrigation systems. The objectives are for students to understand the functions of irrigation systems, sketch different irrigation designs, and appreciate their value. The lesson begins with a review quiz and activity to motivate students. Key terms like furrow, infiltrate, and erosion are defined. Different irrigation designs are then explained, including surface, sprinkler, and drip/trickle systems. Planting layout systems such as square, rectangular, quincunx, triangle, and hexagonal are also defined. Students are asked to sketch irrigation designs and compare the systems in a chart. The homework is to study the next topic in their module.

A. Review
Let’s have a recap aboutthe discussion lastweek.
Direction: Write true if the statement is correct, False if it is
incorrect. Justtype your answer in the chat box.
1. Agricultural inputs are defined as products permitted
for use in organic farming?
2. Farm inputs are the resources used in farm production
such as chemicals, equipmentseeds and energy?
3. Fertilizer are the chemicals or natural substances
added to soil to increase fertility?
4. Seedlings are chemical or natural substances used for
killing insects?
5. Seeds is a flowering plant’s unit ofreproduction
capable ofdeveloping into another plant?
B. Motivation
Before we proceed to our discussion this morning, let’s answer
first the activity I prepared for you.

C. Unlocking of Difficulties
Okay very good!
Now, letus define these words that we’re going to encounter
later. Who can give their ideas aboutdifferent designs of
irrigation center?
furrow- long narrow trench made in the ground by a plow,
especially for planting seeds or for irrigation.
infiltrate- enter or gain access.
erosion- the process oferoding or being eroded by wind,
water, or other natural agents.
c. Lesson Proper
Now, we’re going to tackle the Different designs ofirrigation
center.
Water required by crops is supplied by nature in the form of
precipitation, butwhen it becomes scarce,itis then necessary
to supply itartificially, by irrigation.
Irrigation water management involves determining when to
irrigate, the amount ofwater to supply each irrigation eventand
during each stage of plant and operating and maintaining the
irrigation system.
The primary function of farm irrigation system is to supply
crops with irrigation
water in the quantities and at the time it is needed.
Specific functions include:
1. Diverting water from the water source.
2. Conveying itto individual fields within the farm.
3. Distributing it within each field.
4. Providing a means for measuring and regulating flows.
Other functions offarm irrigation system include crop and soil
cooling, protecting
crops from frost damage, delaying fruit and bud development,
controlling wind erosion, providing water for seed germination,
application ofchemicals, and land application ofwastes.
DIFFERENT DESIGNS OF IRRIGATION SYSTEMS
1. SURFACE IRRIGATION. Water is applied to the field
in either the controlled or uncontrolled manner.
1.1 Furrow irrigation. Only a part of the land surface
is wetted thus minimizing evaporation loss.

3. A. Furrow irrigation by cutting the ridge. A
ridge is the part of the layoutof the field
that is elevated atdifferent angles based
on the type ofsoil. This is actually where
the plants are planted. The furrows are the
troughs that let the water flow through it.
1.2 Border irrigation system is a type ofsurface
irrigation where the field is divided into strips
separated by border ridges running down the
gradientof the field.
1.3 Basin irrigation system. In basin irrigation, water
is flooded in wider areas. It is ideal for irrigating
rice.
Characteristics: A. The area is normally flat.
B. a very high stream size is introduced into the
basin so that rapid movementofwater is obtained.
C. Water does notinfiltrate a lot initially.
D. At the end, a bond is put, and water can pond
the field.
E. The opportunity time difference between the
upward and the downward ends are reduced.
2. SPRINKLER IRRIGATION. The sprinkler system is ideal in
areas where water is scarce. A Sprinkler system conveys water
through pipes and applies itwith a minimum amount of losses.
Characteristics:
a. Water is applied in the form of sprays sometimes
simulating natural rainfall.
b. The difference is that this rainfall can be controlled in
duration and intensity.
c. If well planned, designed,and operated, itcan be used
in sloping land to reduce erosion where other systems
are not possible.
3. DRIP OR TRICKLE IRRIGATION
Characteristics:
a. Water is applied directly to the crop and the 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 reduced evaporation, only potential
transpiration is considered.
f. There is no need for a drainage system.
DIFFERENT TYPES OF PLANTING SYSTEMS:
Planting Systems are also known as Layout Systems which
are ideal for planting fruit crops.
1. Square System. The simplestand easiest type ofplanting
system where trees are planted in four corners that create a
square shape. The distance between rows are the same to the
distance between plants in the same row.
2. Rectangular System. This planting system is somehow
similar to square system where trees are planted in four
corners, butthe distance between rows are more than the
distance between plants in the same row that create a
rectangular shape.
3. Quincunx System. It is also called as Diagonal System.
This system ofplanting is alike to the square system exceptfor
additional tree at the center ofthe square.
Kinds of Trees in Quincunx System:
(Student answer)

4. ▪ Filler Crops. It is called Central Trees because itis found at
the center of the square. These are the trees with shorter life
space. Ifthese trees hindered the full growth of main trees, it
should be uprooted.
▪ Main Crops. It is also known as Main Trees because it
should grow in full size. These trees are found in the four
corners ofa square.
4. Triangle System. It is the system ofplanting where trees
are planted in three angles ofa triangle which provides a wide
space for planting trees.
5. Hexagonal System. It is otherwise known as Equilateral
Triangular System. hexagon with an additional tree at the
center where the distance between tree to tree in six.
6. Contour System. The advisable system ofplanting for the
hilly areas which can avoid soil erosion. Itis somehow similar
to square system and rectangular system, butcontour lines are
created in this type ofsystem as guide for planting the tree
rows using a uniform slope atthe right angles.
