A field trial was carried out at Ibadan, South Western Nigeria in 2001 - 2002 to investigate the biomass, dry matter and mineral composition of Aeschynomene histrix, Centrosema pubescens, Centrosema pascuorum and Lablab purpureus. The experimental design used was completely randomized block design with four replicates for each forage. Average biomass and dry matter yields at 12 weeks after planting were 71.42 and 46.6 t/ha/year, respectively for Lablab purpureus, while such parameters were least in Aeschynomene histrix (4.21 and 2.43 t/ha/yr). Lablab purpureus grew aggressively and vigorously and had the best green and dry matter yields with best leaf stem ratio. Lablab purpureus withstood dry season better than Centrosema pubescens > Centrosema pascuorum > Aeschynomene histrix. These forage legumes were rich in crude protein which ranged from 16.0 % in Centrosema pubescens to 19.7% in Aeschynomene histrix. The most available mineral was calcium in all the forage legumes (0.83 % in Centrosema pascuorum and 1.28 % in Aeschynomene histrix).
