Laboratory experiment was conducted to evaluate the effect of in corporation of rice straw on the germination of different rice cultivars viz: ADT 36,ADT 38,ADT49,CO43.Further the allelopathic impact of crop residues on weed count and weed biomass was also registered. Different rates of incorporation was tried and higher the rate of incorporation, higher the inhibitions on rice and weed observations. Reduction in the performance of rice seed germination and growth parameters was observed with increased rice straw incorporation in all the four rice cultivars tried. Perhaps the rice straw incorporation had an influence on the biomass of rice cultivars too. Supporting research evidences also reveals that allelopathic effect of rice straw on rice and weed performance can stand as a remarkable achievement for recycling rice straw in rice producing countries.
