Information is scanty on seasonal changes in the yield and quality of forage legumes adapted to the West African savannas. Two experiments were conducted from 1992-1994 in the derived savanna zone of West Africa to determine the dry matter (DM) yield and 48-h in sacco DM digestibility of 17 acces...
