摘要:Nigeria has not been able to solve her food problem and the rural dwellers that produces almost the entire food the nation consumed has continued to remain in a poorest condition, despite the millions of naira spent by government on rural and agricultural development. People join cooperative movements to better their economic conditions and other benefits it provides. Cooperatives are different from business organizations because unlike business organizations, cooperatives are more services rented rather than profit oriented. Cooperatives is a voluntary association of individuals who come together to ensure goods and services at cost. When farmers decide to form themselves cooperatives they each extend a part of their business. It is against this backdrop that this paper intends to evaluate the roles of extension in cooperative management and administration in Nigeria.
