Abstract

For many years those now responsible for agricultural development in the savannahs south of the Sahara have searched for methods of intensifying farming. There are some very long-standing projects. Improvements, including animal traction, were introduced from 1929 to the former French Sudan (Mali). Senegalese records show that 130 t fertilizer were applied for the first time to groundnuts in 1949 (Bockelée-Morvan and Vaillan 1968). Improved varieties have been distributed increasingly: “28–206” groundnut, “Souna”, and later “Souna III” millet (Pennisetum), “Blanche de Sefa” and “Jaune de Sefa” maize. From 1960, the newly independent African States, with the cooperation of national agricultural services and agricultural development agencies (BDPA, SATEC, CFDT, etc.) have mounted major extension efforts in the rural areas.
