The four species of legumes used as ruminant feed were Clitoria ternatea (CT), Centrosema pascuorum (CP), Dolichos lablab (DL), and Macroptilium bracteatum (MB). The study was conducted in Randomized Complete Block Design. The research showed that the highest NO concentration after planting was in CP (5.72 mg-1), followed by CT 3 (4.21mg-1), MB (3.44 mg-1), and DL (2.83 mg-1). The species of legume was obviously highly significant (P less than 0.01) to biomass production 90 days after planting. Moreover, dry matter (DM) and organic matter (OM) in vitro digestibility were statistically different among the species of legume (P less than 0.01). In DL the DM and OM were highest i.e., 74.84% and 74.37%. Meanwhile, the biomass digestibility of DM and OM was affected by the treatments (P less than 0.01), being highest in CT (2511.4 g DMm-2 and 2172.1 g OMm-2) followed by DL (2351.8 g DMm-2 and 2044.9 g OMm-2). Based on this study, CT and DL have potential to develop high biomass production, high digestibility, and adequately contribute NO3 to the soil.
