Field experiments were conducted during kharif season of 1997 and 1998 to find out the response of rice to different nitrogen management practices. The results revealed that plant height, tillers, leaf area index and dry matter production of rice were significantly higher with the application of 100% fertlizer N, which was however, comparable with 25%GM N + 75%F N and 25% FYM N + 75% F N in respect of tiner production during later stages and dry matter production during early stages. Application of 100% N through fertilizer recorded the highest number of panicles m−2, panicle length and number of total and filled grains panicle−1, grain and straw yield as wen as nitrogen uptake, which were however, comparable with 25%GM N + 75% F N, in respect of production of panicles and filled grains and also with 25% FVM N + 75%F N, in respect of grain yield.
