This presentation discusses advances in irrigation methods for agriculture. It introduces different types of irrigation systems including flood, sprinkler, and drip irrigation. Flood irrigation involves flooding fields with water through ditches or pipes. Sprinkler irrigation uses pumps to spray water into the air to water crops. Drip irrigation applies water slowly through emitters installed on pipes near plant roots. The presentation examines important factors for irrigation like water availability, crop needs, and climate conditions. It suggests ways to improve irrigation through more efficient water use, soil management, and landscape features to conserve water resources.
Agronomy crops are classified into several categories based on their utilization, including cereal crops, oilseed crops, pulse crops, fiber crops, feed and forage crops, and spices and condiments. Cereal crops like rice, wheat and maize are staple foods, while oilseed crops such as mustard and sunflower are grown for their oil. Pulse crops including green gram and black gram are legumes rich in protein. Fiber crops, feed crops, and spices are also important for various uses. Agronomy studies the management of crop production and combines multiple sciences to understand plant and soil capabilities.
The tests for the evaluation of seedling establishment, palatability and acceptability were carried out at the Teaching and Research Farm of the Department of Agricultural Technology and the Food Laboratory of the Department of Home and Rural Economics, Adamawa State College of Agriculture, Ganye, Adamawa State. The experimental designs used were Randomized Complete Block Design and the Completely Randomized Design. Some of the parameters measured were percentage seedling establishment, palatability, and acceptability tests. The highest mean percentage seedling establishment was observed in 12.00g levels of H. suaveolens whole powder treated shelled groundnut seeds (97.67, 97.00, and 94.00) at the three periods of storage. Percentage seedling establishment decreased with a decrease in levels of H. suaveolens whole powder. One of the major constraints to the use of plant materials as an alternative to synthetic insecticides is the issue of standardization in dosage of application. This work has suggested that, if groundnut seeds are to be used for sowing, they should be stored with a 12.00g level of H. suaveolens whole powder for every 300.00g for three months. However, if they are to be used for consumption, they could be stored with a 6.00g level of H. suaveolens whole powder for every 300.00g for at most three months. There was no significant difference between treated and untreated shelled groundnut seeds at the three periods of storage on the acceptability and palatability score of cooked groundnut at all dosages of application. All treatments were within the acceptable score rates even though the two rates of the synthetic insecticides, actellic dust were at the lowest acceptable score rate. The finding also showed that acceptability and palatability decreased with an increase in dosage of application. The periods of storage also had a significant impact on the mean percentage seedling establishment. It was observed that there was a higher percentage of seedling establishment when shelled groundnut seeds were stored from November- January. At this period of the year, the temperature and humidity are usually low and this might have necessitated the high state of inactivity and low performance of the bruchids compared to other periods of storage within the year.
Prior to planting, the soil needs to be prepared through tillage or herbicides to kill weeds. There are three main tillage categories - conventional, reduced, and conservation - depending on how much crop residue is left on the surface. Conservation tillage, including no-till, leaves at least 30% residue coverage and places seeds directly into last season's crop residue without disturbing the soil. Herbicides are used in all tillage systems to control weeds. Tillage generally occurs between harvest and spring planting, though the optimal time is just before planting to reduce soil erosion. Late planting can significantly reduce crop yields.
Using techniques of modern biotechnology such as gene transfer, crop yields can potentially be increased by imparting traits that enhance growth. However, increasing yields is difficult as it involves many genes, each with a small effect. Biotechnology also aims to develop crops with increased stress resistance, nutritional quality, taste/appearance, and reduced dependence on fertilizers and pesticides. However, increased herbicide use from herbicide-resistant crops is a concern.

1) Dryland cereals like sorghum and millet are important staple crops for over 500 million people in Africa and Asia. They are drought tolerant and can be grown in harsh environments where other crops cannot.
2) Demand for these crops is increasing due to population growth and new markets. However, production is constrained by drought, degraded soils, pests, and lack of improved varieties.
3) The organization is working to develop more resilient varieties of sorghum and millet using modern breeding techniques like high-throughput phenotyping and genomic tools to integrate drought tolerance and other traits. This will help meet the projected 40% increase in demand for these crops by 2020.

3. 2.0 ABSTRACT
There have been continuous improvement in the approach to today’s agricultural
development worldwide in the aspects of the productions methods, technology adopted to
increase the efficiency of production and input of appropriate resources such as research and
knowledgeable human capital including scientists, inventors, engineers, chemists and economists
although many have nothing to do with food production. Modern agriculture incorporates many
disciplines of sciences such as agronomy, horticulture, breeding, genetics, entomology,
pathology, soil science, environment science, livestock management, pasture management, meat
science,dairy science, aquaculture, biotechnology, engineering and many more.
There are several ways of comparing the agricultural economy of one region with that of
another. It can be done in terms of crop distributions, or relative productivity, or the effect on the
rural landscape. The method used here will be a classification of agricultural practice in terms of
the basic method or technology by which the farmer tackles the job of wresting crops from the
earth. Agricultural technology, as it functions in various natural settings, not only influences crop
patterns, productivity, and the landscape, but also affects population density, possibilities for
trade and urbanization, and social structure. If we look around the world and attempt to plot on a
map the varying techniques with which different societies face the fundamental tasks of
cultivation, we are bound to be struck by the existence, over wide areas containing many
millions of people, of relatively unsophisticated techniques that seem to be survivals from an age
which the more sophisticated societies have left far behind. There are today but few regions
where these unsophisticated techniques are entirely unaffected by new ideas that have spread
with modern trade and commerce from those countries with early experience of agrarian
revolution. The degree of penetration by these new ideas varies widely, however, from place to
place.

4. 3.0 INTRODUCTION
3.1 Definition and Type of Agriculture
The word agriculture is the English adaptation of Latin agricultura, from ager, means “a
field” and cultura, means “cultivation” in the strict sense of “tillage of the soil”. It is the
utilization of natural resourse systems to produce commodities which maintain life, including
food, fiber, forest products, horticultural crops, and their related services.
Practices in agriculture can be broadly catagorised into two types that is subsistence
farming and commercialised farming. The subsistence farming is characterized by a low input
with a resultant low yield and inter-cropping. Practices may involve slash and burn nomadic and
more progressive stationary cultivation. Subsistence farming involves working on a plot of land
to feed the family working on it to produce enough food. The one examples of the type of
farming is the shifting cultivation that is an agricultural system in which plots of land are
cultivated temporarily, then abandoned. This system often involves clearing of a piece of land
followed by several years of wood harvesting or farming, until the soil loses fertility. Once the
land becomes inadequate for crop production, it is left to be reclaimed by natural vegetation, or
sometimes converted to a different long-term cyclical farming practice. The ecological
consequences are often deleterious, but can be partially mitigated if new forests are not invaded.
Raising domesticated livestock for food and small profit, mostly limited to free-range and small
enclosures, is now practiced. Subsistence farming (as of 2006) is still practiced in many countries
in Africa, Central and South America, Polynesia an South East Asia.
Besides, the commercialised farming also can be characterisedby monoculture or a
cultivation of a combination of a few crops. It entails the usage of high yielding modern
varieties, large chemical input (pesticides and fertilizers and animal feeds), high technology and
extensive mechanization. The examples of the commercial that are discussed is tropical
plantation agriculture that solely a monocropping system dominated by perennial crops which
include rubber, oil palm, cocoa, coffee, coconut and tea. Second, the vegetable farming that is
the labour intensiveand involves specialized cultivation in rows and blocks (beds) open or
enclosed. Third, the organic farming that involves crop rotation where dissimilar crops are grown
on the same plot in sequential seasons to avoid building up of pests and diseases.Next, the
4
5. hydroponics that is the technique of growing plants with taking advantage of the fact that plants
absorb nutrients as simple ions in water. Then,the aquaculture that is a purposeful cultivation of
aquatic organisms as opposed to simple catching them from the wild.The livestock farming
involves raising livestock (domesticated animals intentionally reared in agricultural setting) to
make products such as food or fibre, or for its labour. Last but not at least, the new products and
future industries as envigased in the Third National Agricultural Policy (NAP3), the
development of biotechnology poducts, extraction of specialty natural chemicals from biological
resources and utilization of oil palm biomass are emphasized to create new higher value
industries.
3.2 Productivity of Agriculture
The primary products from the agricultural industries can be specifically into two part
that food products (animal and plant origin) and non-food products animal and plant origin).
Many of these raw agricultural products undergo further processing usually on industrial scale to
produce varieties of products for human (food and non-food) and animal (as feed) use.
Therefore, the finished products are primarily sourcedfrom either plants and animals. In the plant
origin for the food processing, fruits are processed for their juices, cordials, jems and jelly,
herbal and health products an as pickled and dehydrated ware. Other sources processed include
rice, sugar, spices, cereals, tomatoes, chillies and cocoa. Foods could be packed, canned or
bottled as in the case of candies, ketchup, cookies and crips. For the non-food products or
industrial processing, timber can be processed into furnitureand building materials; rubber latex
can be turned into tyres, gloves, shoes and condoms; palm oil is used for making margarines,
toiletries, cosmetics, carotenes and biofuel; cotton and linen are processed into apparels. Besides,
in the animal origin for food processing, meats are processed into burgers, sausage and nuggets.
Fish are dried, slated or canned such as sardines. Dairy produced can be processed as powders,
canned milk, cheeses and fermented beverages. For theindustrial processing, leather and silk are
made into apparel, footwear,belts, handbags and wallets.

6. 3.3 Tecnology of Agriculture
There are several challenges in agriculture such as labour, price, crop choice, resources
and agricultural technology but the focus here is the agricultural technology and similarly with
the main idea of this title. Agricultural technology is the application of the principles of
mathematics and natural sciences in order to be economically efficient use of agricultural
resources and natural resources for human welfare. The types of agricultural technology are the
genetic engineering, tissue culture, biotechnology, conventional method, and precision
agriculture. The benefits from prospecting and developing the potentials and applications of new
and frontier technologies are yet to be realized.
Among these are the use of plant cell and tissue culture techniques as well as genetic
engineering to complement conventional plant breeding in developing new crop varieties.
Second, the use of plant cell cultures to enhance the development of new and innovative products
including metabolites such as pharmaceuticals, nutriceuticals and food additives. Third, the
application of embryo manipulation technology and the use of genetically engineered vaccines to
strengthen existing technologies for existing technologies for increasing animal productivity.
Next, the incorporation of robotics and artificial intelligence as well as computer modeling,
including expert systems and computer simulated scenario analysis and microprofessor control in
machinery and automation equipment to reduce labour. Lastly, the application of advance
processing and packaging systems to strengthen and enhance conventional and traditional
techniques for better post-harvest handling and storage and longer shelf-life of agricultural
products.

7. 4.0 AGRICULTURAL TECHNOLOGY
4.1 Genetic Engineering
Genetic engineering, also called genetic modification, is the direct manipulation of an
organism's genome using biotechnology. New DNA may be inserted in the host genome by first
isolating and copying the genetic material of interest using molecular cloning methods to
generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the
host organism. Genes may be removed, or "knocked out", using a nuclease. Gene targeting is a
different technique that uses homologous recombination to change an endogenous gene, and can
be used to delete a gene, remove exons, add a gene, or introduce point mutations.
One of the best-known and controversial applications of genetic engineering is the
creation and use of genetically modified crops or genetically modified organisms, such as
genetically modified fish, which are used to produce genetically modified food and materials
with diverse uses. There are four main goals in generating genetically modified crops. One goal,
and the first to be realized commercially, is to provide protection from environmental threats,
such as cold (in the case of Ice-minus bacteria), or pathogens, such as insects or viruses, and/or
resistance to herbicides. There are also fungal and virus resistant crops developed or in
development. They have been developed to make the insect and weed management of crops
easier and can indirectly increase crop yield. Another goal in generating GMOs, is to modify the
quality of the produce, for instance, increasing the nutritional value or providing more
industrially useful qualities or quantities of the produce. The Amflora potato, for example,
produces a more industrially useful blend of starches. Cows have been engineered to produce
more protein in their milk to facilitate cheese production. Soybeans and canola have been
genetically modified to produce more healthy oils. Another goal consists of driving the GMO to
produce materials that it does not normally make. One example is "pharming", which uses crops
as bioreactors to produce vaccines, drug intermediates, or drug themselves; the useful product is
purified from the harvest and then used in the standard pharmaceutical production process. Cows
and goats have been engineered to express drugs and other proteins in their milk, and in 2009
the FDA approved a drug produced in goat milk.
7
8. Another goal in generating GMOs, is to directly improve yield by accelerating growth, or
making the organism more hardy (for plants, by improving salt, cold or drought tolerance). Some
agriculturally important animals have been genetically modified with growth hormones to
increase their size. The genetic engineering of agricultural crops can increase the growth rates
and resistance to different diseases caused by pathogens and parasites. This is beneficial as it can
greatly increase the production of food sources with the usage of fewer resources that would be
required to host the world's growing populations. These modified crops would also reduce the
usage of chemicals, such as fertilizers and pesticides, and therefore decrease the severity and
frequency of the damages produced by these chemical pollution.Ethical and safety concerns have
been raised around the use of genetically modified food. A major safety concern relates to the
human health implications of eating genetically modified food, in particular whether toxic or
allergic reactions could occur. Gene flow into related non-transgenic crops, off target effects on
beneficial organisms and the impact on biodiversity are important environmental issues. Ethical
concerns involve religious issues, corporate control of the food supply, intellectual property
rights and the level of labeling needed on genetically modified products. Here is the photo of one
of the peanut leaves that applied from this technology:

Genetic engineering can be used when insufficient natural variation in the desired
nutrient exists within a species. Box 9 describes the debate surrounding a project to enhance the
protein content of potato using genetic engineering. The well-known transgenic Golden Rice
contains three foreign genes - two from the daffodil and one from a bacterium - that produce
provitamin A . Scientists are well on their way to developing transgenic “nutritionally
optimized”' rice that would contain genes producing provitamin A, iron and more protein
(Potrykus, 2003). Other nutritionally enhanced foods are under development, such as oils with
reduced levels of undesirable fatty acids. In addition, foods that are commonly allergenic
(shrimp, peanuts, soybean, rice, etc.) are being modified to contain lower levels of allergenic
compounds.
9
10. A major technical factor limiting the application of genetic modification to forest trees is
the current low level of knowledge regarding the molecular control of traits that are of most
interest. One of the first reported trials with genetically modified forest trees was initiated in
Belgium in 1988 using poplars. Since then, there have been more than 100 reported trials
involving at least 24 tree species, primarily timber-producing species. Traits for which genetic
modification has been contemplated for forest trees include insect and virus resistance, herbicide
tolerance and lignin content. Reduction of lignin is a valuable objective for species producing
pulp for the paper industry because it would enable a reduction in the use of chemicals in the
process.
Growth in adoption of genetically engineered soybean, cotton, and corn in the United States,
1996-2009. HT = Herbicide-tolerant crops; Bt = Insect-resistant crops containing Bacillus
thuringiensis genes. Each category includes crops with both traits.

11. 4.2 Tissue Culture
Just as every person is different and unique, so is each plant. Some havetraits like better
color, yield, or pest resistance. For years, scientists havelooked for methods to allow them to
make exact copies of these superiorindividuals.Plants usually reproduce by forming seeds
through sexual reproduction.That is, egg cells in the flowers are fertilized by pollen from the
stamens ofthe plants. Each of these sexual cells contains genetic material in the form ofDNA.
During sexual reproduction, DNA from both parents is combined in newand unpredictable ways,
creating unique plants.This unpredictability is a problem for plant breeders as it can take
severalyears of careful greenhouse work to breed a plant with desirablecharacteristics. Many of
us think that all plants grow from seeds. However,researchers have now developed several
methods of growing exact copies of plants without seeds. They also are now doing this through a
method called “tissue culture”.
Tissue culture (TC) is the cultivation of plant cells, tissues, or organs on specially
formulated nutrient media. Under the right conditions, an entire plant can be regenerated from a
single cell. Plant tissue culture is a technique that has been around for more than 30 years. Tissue
culture is seen as an important technology for developing countries for the production of diseasefree, high quality planting material and the rapid production of many uniform plants.
Micropropagation, which is a form of tissue culture, increases the amount of planting material to
facilitate distribution and large scale planting. In this way, thousands of copies of a plant can be
produced in a short time. Micropropagated plants are observed to establish more quickly, grow
more vigorously and are taller, have a shorter and more uniform production cycle, and produce
higher yields than conventional propagules. Plant tissue culture is a straightforward technique
and many developing countries have already mastered it. Its application only requires a sterile
11
12. workplace, nursery, and green house, and trained manpower. Unfortunately, tissue culture is
labor intensive, time consuming, and can be costly. Plants important to developing countries that
have been grown in tissue culture are oil palm, plantain, pine, banana, date, eggplant, jojoba,
pineapple, rubber tree, cassava, yam, sweet potato, and tomato. This application is the most
commonly applied form of traditional biotechnology in Africa.
High Yield
Yields of adherent cells grown in Millicell HY cell culture flasks are linearly proportional to
surface area and closely match theoretical yields. CHO-k1 cells seeded at 40,000 cells/cm2,
propagated with 0.2 mL/cm2 culture medium and incubated for 48 hours at 37 ºC, 6% CO2, 95%
relative humidity. Cells were washed with 0.02% EDTA followed by harvest via enzyme
dissociation for 10-15 minutes at 37 ºC. Cell counts were normalized to average cell yield from
T75 flasks and reported as T75 flask equivalents. Perfectly uniform cell growth on each layer for
results we can count on:
12
13. Theoretical cell yield = (total surface area in cm2) divided by 75 cm2. Separating the layers of a
5-layer Millicell HY cell culture flask shows perfectly uniform cell growth across all 5 layers.
Adherent cells were stained prior to flask disassembly.
4.3 Biotechnology
Biotechnology has many applications in agriculture, including diagnostics, vaccines and
therapeutics for animal health; DNA fingerprinting for managing animal stocks and identifying
specific plant varieties, animal and plant propagation; and the use of marker assisted selection,
intragenics and genetic modification (GM) to develop improved plant and animal varieties. The
term agricultural biotechnology encompasses a variety of technologies used in food and
agriculture, for a range of different purposes such as the genetic improvement of plant varieties
and animal; genetic characterization and conservation of genetic resources; plant or animal
disease diagnosis; vaccine development; and improvement of feeds (FAO,2009a). Some of these
technologies may be applied to all the food and agricultural sectors, such as the use of molecular
markers or genetic modification, while others are more sector-specific, such as tissue culture (in
transgenic crops and forest trees), embryo transfer (livestock) or sex-reversal (fish).
Biotechnology has the potential to increase crop and animal productivity to improve
nutritional quality, broaden tolerance of crops for drought, salinity, and other environment
related stresses and increase resistance of crops to pests and diseases. Malaysia has a long
tradition as a leader in tropical plantation technology. Agriculture is still the backbone of the
Malaysian economy, the nation has moved from traditional agriculture toward a modern outlook
of the sector. Agricultural biotechnology answers the drive to ensure sample food supply and a
sustainable production of food for Malaysia.
Biotechnology is already being applied to increasing yield in the region by
• Minimizing pre- and post-harvest losses
• Increasing actual yields closer to the current production potential; and
• Increasing the production potential.
13
14. Examples include the use of in-vitro culture techniques in potatoes, cassava and
plantation crops, haploids in rice, diagnostic kits for disease identification, new and recombinant
vaccines and embryo transfer. Other examples are, transgenic fish through chromosome set
manipulation for polyploidy induction, and improved breeding induction and hypophysation,
hybridization, for example, of catfish, use of probiotics in feed, fish pond and fish health
management. In some countries in the region, commercial production of transgenic cotton and
soybean is increasing fast. These techniques provide opportunities for refining, standardisation
and efforts to increase cost-effectiveness to improve their transfer to and adoption by the
majority of small farmers. Biotechnology also has been recognized as one of the new high
technologies that will bring about desired changes in the agricultural sector. The sector aims to
increase productivity and yield of agriculture produce; the diagram below shows the aspiration of
production of key agriculture produce under the 3rd National Agriculture Policy and the 9th
Malaysia Plan. It is also a revolutionary technology which employs advanced processing
methods and genetically modified organisms to improve yield and quality. It providesnew food
materials for consumers and environmentally friendly ways of pests and disease control.
Examples can be seen in the production of high yielding clones, fast and frozen foods,
dehydrated fruits, nutriceuticals, antioxidants, vitamins, cosmetics and enzymes.

duplicate cultures per clone at 24 h intervals are shown. The low yielding clones grew faster and
to a higher cell density than the control and high yielding clones. Error bars for cell counts
(typically 15%, Nielsen et al., 1991), are not shown for clarity.

16. 4.4 Conventional Method
It is hard to put a single definition to conventional farming, as the term is used to describe
a wide range of agricultural practices. In general it is assumed to be any type of agriculture that
requires high external energy inputs to achieve high yields, and generally relies upon
technological innovations, uniform high-yield crops, and high labor efficiencies. Many view
conventional agriculture less as a defined practice and more as a philosophical idea based on
industrial agriculture.Conventional agriculture typically has strong impacts on the diversity,
structure, and roles of small mammal populations. Overall, conventionally managed agricultural
fields have lower a lower biodiversity of small mammals than sustainably managed fields Also, a
lower abundance of small mammals is often prevalent; a study of bats showed that abundance
decreased with the increase in agricultural intensity This is often due to the high use of pesticides
and herbicides, which can eliminate essential habitat (ground cover) and food sources (green
vegetation or insects). Dietary shifts to lower quality food, dispersal to new areas, and lowered
reproductive success have also been noted in certain small mammals.
Conventional agriculture can also aid more disturbance-adapted species, such as deer
mice and house mice. These species can often be more beneficial as insect pest and weed seed
predators than detrimental as crop pests. Furthermore, known agricultural pest species such as
meadow voles and prairie voles are not well adapted to living in conventional fields. Their
presence, if any, will be at the uncultivated edges of the fields, leading to virtually no detrimental
impact on agricultural yields.
Example of a tilled field near Northfield, MN
While the tillage system is not necessarily exclusive to this type of agriculture, tilled fields are
more often found in conventional agriculture than sustainable agriculture, and impose many of
16
17. the same effects on small mammal populations as conventional agriculture does. Tillage is when
the soil in a field is ploughed in order to reduce weed species and aid in planting. Tilled fields
typically have lower species diversity, but with higher abundances of disturbance adapted
species, such as the deer mouse, than do no-till fields. Similar to conventional agriculture, these
species can often be more beneficial as pest and weed species controllers than detrimental to
crops. Tilling also helps keep down pest species, such as prairie voles and meadow voles, which
rely upon thick ground cover. These two species, if in large enough numbers, can cause serious
economic problems

Organic farming is the process by which crops are raised using only natural methods to
maintain soil fertility and to control pests. The amount of crops produced by conventional
farming methods is often larger than that of organic farming. But conventional farming, with its
heavy use of manufactured fertilizers and pesticides (agrochemicals), has a greater negative
effect on the environment. In comparison, organic farming produces healthy crops while
maintaining the quality of the soil and surrounding environment.
Animal Husbandry
In conventional farming, livestock animals are generally kept together under extremely
crowded and foul conditions. Because of this, they are highly susceptible to diseases and
infections. To manage this problem, conventional farmers rely on antibiotics, which are given
not only when animals are sick but often on a continued basis in the animals' feed. Since the mid-
17
18. 1990s, however, scientists have known that this practice has led to the development of new
strains of bacteria that are resistant to the repeated use of antibiotics. These bacteria are not only
harmful to the animals but are potentially harmful to the humans who consume the animals.
Organic farmers might also use antibiotics to treat infections in sick animals, but they do not
continuously add those chemicals to the animals' feed. In addition, many organic farmers keep
their animals in more open and sanitary conditions. Animals that are relatively free from
crowding and constant exposure to waste products are more resistant to diseases. Overall, they
have less of a need for antibiotics.

Some conventional farmers raising livestock use synthetic growth hormones, such as
bovine growth hormone, to increase the size and productivity of their animals. Inevitably, these
hormones remain in trace concentrations, contaminating the animal products that humans
consume. Although risk to humans has yet to be scientifically demonstrated, there is controversy
about the potential effects. Organic farmers do not use synthetic growth hormones to enhance
their livestock.

19. 4.5 Precision Agriculture
The term precision agriculture is applicable to any form of information gathering,
management, planning, or field operation that improves the understanding and management of
soil and landscape resources so that cropping inputs or management practices are utilized more
efficiently than with conventional “one -size-fits-all”strategies. Essentially, precision agriculture
involves the management of spatial and temporal variability associated with all aspects of
agricultural production in order to improve crop performance and environmental quality this is
strategically achieved by matcing agricultural inputs and practices to localized conditions within
a field (site-specific management).
Precision agriculture has three fundamental requirements, which are
i)
ability to identify each field location
ii)
ability to capture, interpret and analyze agronomic data at an appropriate scale
and frequency
iii)
ability to adjust input use and farming practices to maximize benefits from each
field location
A suite of technologies such as Global Positioning Satellites (GPS), Geographical
Information System (GIS), remote sensing, Variable Rate Technology (VRT),on-the-go
sensors, grid sampling, and yield monitors is used to fulfil these requirements. Protocols
for precision agriculture implemention are:
i)
gathering information about variability
ii)
processingand analyzing information to access the significance of
variability
iii)
implementing change in the management of inputs
Precision agriculture subscribes to a cyclic process that is typified by a system
that gets smarter every year a field/farm operator uses it.

20. Implementing practices to address variability
New information and communication technologies (NICT) make field-level crop
management more operational and easier to achieve for farmers. Application of crop
management decisions calls for agricultural equipment that supports variable-rate technology
(VRT), for example varying seed density along with variable-rate application (VRA) of nitrogen
and phytosanitary products.Precision agriculture uses technology on agricultural equipment (e.g.
tractors, sprayers, harvestors, etc.): positioning system (e.g. GPS receivers that use satellite
signals to precisely determine a position on the globe); geographic information systems (GIS),
i.e., software that makes sense of all the available data; variable-rate farming equipment (seeder,
spreader).

22. 5.0 CONCLUSION
Agricultural technologies and knowledge have, until recently, largely been created and
disseminated by public institutions. But over the past two decades, biotechnology for agricultural
production has developed rapidly, and the world economy has become more globalised and
liberalised. This has boosted private investment in agricultural research and technology,
exposing agriculture in developing countries to international markets and the influence of
multinational corporations. But the public sector still has a role to play, particularly in managing
the new knowledge, supporting research to fill any remaining gaps, promoting and regulating
private companies, and ensuring their effects on the environment are adequately assessed.
If the public sector focuses on these four topics that knowledge management, gap-filling
research, promoting and regulate the private sector, and lastly environmental impact analysis, it
will continue to support relevant transfers of agricultural technology. In particular, public sector
organisations need to join forces with the private sector to provide reliable funding and sources
of trained personnel to improve agricultural technology policy in developing countries.This
should occur in cooperation with international mechanisms, like CGIAR, and research
institutions in the developed world. Agricultural innovation has always come from collaborations
between public institutions, the scientific community and agriculturalists themselves. Now, with
the private sector's growing importance in the innovation process, the challenge facing the public
sector is to bridge the gap and work with these new players.
