This study was held in order to investigate biomass production, nutrient quality, and in-vitro digestibility of legume in both 90 and 120 days after planting (DAP). The method used was experimental study using Completely Randomized Design (CRD) with 8 herbaceous legume as treatment and 4 replication of soil fertility or in another word 32 trials. At in-vitro investigation, method used was CRD with 8 herbaceous legume as treatment and 3 replication of rumen fluid. The results showed that herbaceous legume had very significant different (P<0.01) on Dry Matter (DM), Organic Matter (OM), and Crude Protein (CP) for both 90 and 120 DAP herbaceous legume. The highest production in 90 DAP was CT cv. Milgarra (4,577.6 kg DM/ha), while the lowest was C. molle (783 kg DM/ha). At 120 DAP, the highest production was S. seabrana (6,739.2 kg DM/ha), while the lowest was LP cv. Highworth (1,293.6 kg DM/ha). Further investigation reported that herbaceous legume had very significant effect on DM, OM, and CP digestibility for both 90 and 120 DAP. The highest average production of DM, OM, and CP for both 90 and 120 DAP were CT Q5455 and CT cv.Milgarra. Different result was showed by LP cv.Highworth and MB cv.Cadaarga which declined at 120 DAP. Additionally, CP cv.Bundey, MB cv.Juanita, C. molle, and S. seabrana at 120 DAP which was consisten with the production of DM, OM, and CP. In conclusion, herbaceous legume CT cv. Milgarra, CT Q5455 and S. seabrana had high productivity (the highest OM digestibility) at 90 and 120 DAP, while highest cumulative forage production were CT cv. Milgarra, CT Q5455, and S. seabrana.
