Loamy soil is the type of soil that has
moderate water infiltration and retention
abilities good for cassava growth.
.
3aii)
i)Clear land of all grass, brush and trees
ii)Plough, rotovate and ridge
iii)Apply limestone at 2-4 t/ha before
rotovating
iv)Form ridges 1m apart and 25-40 cm high
.
3aiii)
Cassava is propagated by cuttings, by
planting pieces of stem.
.
3aiv)
Setts are planted 50 cm to 90 cm on the ridge
at a 45o angle leaving 2-3 nodes above
ground.
.
3av)
Use a contact and/or pre- emergent herbicide to control weeds for the first three months of growth (vegetative stage).
Hand-weeding using hoes are normally
recommended after 3 months, if necessary,
since the enlarged crop canopy should limit
weed growth after 3 months.
.
3avi)
When soil tests are not done, a general
recommendation for fertilizing cassava can
be: a. NPK (12:24:12) applied at the rate of
336 kg/ha at 6 weeks after planting followed
by 16:8:24 at 16 weeks after planting
.
3avii)
Cassava matures between 8 to 12 months
after planting. Cutting back plants 2 weeks
before harvesting should cause tubers to
mature and increase yields by 10%. Do not
weed before harvesting.
.
3aviii)
The storage method include its use in the
productions of garri, farinha, attieke, cassava
bread, chips, cassava powder
.
·2a) -Availability of water(Rainfall) -Availability of source of water for irrigation -The type of soil or land where irrigationis to be carried out -Availability of machine for installation -Technical know how
.
2b) -Inadequate water supply or source of water -High cost of equipment -Lack of adequate technical know how -Excessive dissolution of salts in irrigated water prevent proper growth -Disturbance of movement of farm machinery

.
2dii) -Harrow(Disc harrow) -Ridger -Cultivator
.
5a) Anthrax:
(i)-Bacillus anthracis
(ii)-Via respiration ie air borne
(iii)-Small blisters on skin,vomiting,diarrhea (iv)-Use of antibiotics -Killing and burrying of infected animals
.
5bi) -Fish meals -Blood meal -Soya bean cake Groundnut cake
.
5bii) -Field peas -Alfalfa
.
5c) -It is mobile -It is perishable -Its supply is inelastic -Its reward is wage and salary -It is a physical and mental effort on man
.
(6a)
i.By washing of the feeders and drinkers regularly
ii.Admistration of vaccine and medication to birds
iii.Fumigation and proper sanitation should be done before arrival of the bird
iv.Provision of medication and vaccination
.
(6b)
-It prevents secondary infection caused by horn injuries
-It creates more space for animals
-It prevents injuries to the body of other animals
-It makes it safer during vaccination or deworming of animals
.
(6c)
- harvesting
- packaging and packing
- transport
- advertising
- food processing
.
(6d)
-Inadequate for land tenure system
-inadequate finance and credit facilities
-poor marketing system
-inadequate farm input
.
4a)
LAND TENURE SYSTEm: is a system in which a party occupies or holds some area of
land.
.
4b)
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place"
.
4C)
i)Rootknot nematode/Meloidogyne spp.
ii)
-Nematodes are soil borne so are transmitted through soil movement and run-off water
-Through vegetative planting materials/
transplanting of seedling
-Through contaminated farm tools and equipment
.
iii)
-Enlargement of certain cells of the
-roots in the form of knots
iv)
-Crop rotation
-Use resistant varieties
.
(1ai)
Basic Ammenities:
-It makes able bodied me to migrate from rural to urban areas in search of job
-Poor processing facilities for farm produce
-Shortage of water for irrigation purposes for all season cropping
-Poor health services reduces the productivity of farmers
.
(1aii)
Farm inputs:
-Available farm inputs are of inferior quality,outdated and crude
-Farm inputs like chemicals,fertilizers,tools and implements are grossly inadequate
-Modern farm inputs are not produced in Nigeria
-Farm inputs are expensive to buy and maintain
