(i)Land tenure system: The type of land
tenure system (communual) does not

(ii)Scattered farm holdings: Scattered
farm holdings are also not conducive or
economical for mechanisation,
especially in Nigeria.
(iii)Poverty of farmers: Most farmers,
especially in Nigeria are very poor and
cannot afford the cost tractors and farm
implements.
(iv)Inadequate facilities (machinery):
The facilities or machinery for
fabricating and repairing farm
implements are grossly insufficient
where they are available.
(v)Bad topography: The topography of
most Nigeria landscape is too rough
and unconducive for farm
mechanisation.
(1c)
(i)Inadequate finance
(ii)Poor infrastructure
(iii)Land tenure system
(iv)Poor technical support
(v)Unpredictable weather
(viPoor disease control methodology

maintain landscapes.
(ii)helps to grow agricultural revegetate
disturbed soils in dry areas and during
periods of less than average rainfall.
(iii)it also help in controlling the
amount of water can be supplied
through artificial means such as pipes,
ditches, sprinklers etc.
(iv)It also help plant absorb mineral
nutrients from the irrigated soil. In other
words it is essential for the general
growth of the plant.
SECTION C

Better Than The. Older Ones
(5aii)
(i)To improve the quality of produce.
(ii)To increase crop yield.
(iii)To adapt crops to adverse climatic
conditions.
(iv)To induce resistance to pests and
diseases in crop plants.
(v)To conserve land. resources.
(5b)
(i)Use of prepared beds.
(ii)Use of nylon bags.
(5c)
(i)population growth
(ii)land availability
(iii)Farm labour supply
(5d)
(i)Cutting
(ii)Division
(iii)Grafting
(iv)Layering
SECTION D
(8a)
(i)It helps in saving the feed and water.
(ii)It brings about uniformity of the
stock.
(iii)It reduces the cost of production and
increases the farmer’s profit.
(8b)
(i)they are grazed by domestic livestock
or wild animals.

vegetation
iii)Rangelands do not include forests

SECTION E
(9ai)
-Farmily Labour-
(i)It is cheap
(ii)Farm size are usually small
(9aii)
-Working Capital-
(i)Short-Term Needs
(ii)Circular Movement
(9b)
(i)Shortage of supply; This is because
lowered prices can lead to a sudden rise
in demand that many producers may
find very hard to meet. Ultimately, it can
lead to very high demand that causes an
increase in prices.
(ii)Difficulty in measuring success; if the

(iii)Higher taxes; the government raise
funds to the farms and Agricultural
production agency to use for subsidizing
industries? Of course, by imposing
higher taxes. So, it is the people who
provide the means to enable the
government to subsidize industries.
(iv)market cycle towards farm subsidies;
Raising the income while prices are
rising will eventually raise commercial
and industrial costs, causing the final
products to lose their competitiveness in
the international market.
(9c)

activities, such as planting, irrigation,
chemical application, harvesting,
grading, payroll, and record keeping.
(ii)Contracts with farmers or
independent owners for raising of crops
or for management of crop production.
(iii)Coordinates growing activities with
those of engineering, equipment
maintenance, packing houses, and other
related departments.
(9d)

understanding of complex skills and
principles.
(ii)Students can pay their attention and
follow along with the learning process.
(iii)Knowledge becomes permanent
because this method requires different
human senses.
(iv)Students are motivated to study and
gain necessary skills.
