A field study was conducted to assess the effect of grass and legume intercropping on the biomass yield, quality and soil fertility during monsoon, 2004. A maximum biomass production (487.61g m-2) was recorded for grass-legume mixture with the ratio of 40:60, respectively followed by grass alone (419.05g m-2). Lowest biomass yield (387.87g m-2) was given by the legume alone. A 40:60 ratio mixture of grass and legume attained the greatest plant height (108.88 cm) followed by the 60:40 ratio mixture (100.11 cm). Maximum crude protein percentage (15.46 %) was recorded in 40:60 ratio mixtures of grass and legume, while the minimum one in grass alone. Maximum soil nitrogen (0.051 %) was determined in legume alone followed by (0.045 %) in 40:60 ratio of grass-legume mixture, while it was the minimum in grass alone at 0 - 15 cm and 15 - 30 cm soil.
