(a) Roles of agricultural extension in agricultural development in West Africa:
– Provides effective linkage between researchers and farmers.
– Serves as a two-way line of communication between policymakers (government) and farmers.
– Provides an opportunity for farmers to adopt improved farming methods, techniques and innovations.
-Enables farmers to be aware of support services available to them, including financial assistance /farm inputs.
– Helps farmers to become competent and confident to confront their farming problems at the individual level.
– Helps to supervise the beneficiaries of agricultural loans.
– Assists in the supervision and evaluation of agricultural development programmes.

– Illiteracy of the farmers.
– Inadequate/poor transportation facilities.
– Inadequate extension workers.
(c) Discussion on the cultivation of groundnut:
(i) Soil requirements:
– Requires well-drained/sandy loam soil.
– Requires soil rich in calcium and phosphorus.
(ii) Method of propagation:
– Propagated by seed.
(iii) Methods of storage:
– Dried unshelled groundnut seeds are packed into dry bags or sacks.
– Dried groundnut seeds can be stored in clean rhombus or silos.
– Dried clean pods are stored in baskets, pots, earthen bins, or drums.
– Dried groundnut seeds can be stored in silos.
(d) Field pests and storage pests of maize:
– Stern borer
– Rat/ mouse.
