The agricultural extension system is an important actor in agricultural and rural development efforts in Nigeria. Extension activities are implemented by the Agricultural Development Programmes (ADP) and other civil societies, private and university-based extension service providers. The ADP, which basically used extension approaches, has impacted in so many ways on the target populace and has been adopted by all state governments in the country. Several dissemination methods have been used in the history of the institution’s activities, which include the ministry-based conventional system, commodity-based system, university extension system and the current integrated agricultural development approach.
