Abstract :The study was conducted at the experimental field of the Department of Soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University insert ignore into journalissuearticles values(BSMRAU);, Gazipur, Bangladesh during July to November 2015 in transplanted aman insert ignore into journalissuearticles values(T. aman); season to evaluate the influence of rice straw application on growth and yield of rice insert ignore into journalissuearticles values(BINA dhan7); and soil fertility. The experimentation was established following a randomized complete block design insert ignore into journalissuearticles values(RCBD); using 3 treatments insert ignore into journalissuearticles values(T1= Inorganic fertilizer dose as per STB, T2= rice straw + inorganic fertilizer as IPNS basis and T3= Farmer’s practice);. Results of the experiment showed that application of rice straw along with inorganic fertilizers as IPNS basis did not produce any significant insert ignore into journalissuearticles values(p<0.05); variation in yield and yield regulating parameters of T. aman rice but ensured higher filled grains panicle-1 insert ignore into journalissuearticles values(96.68);, 1000- grain weight insert ignore into journalissuearticles values(23.23g);, straw insert ignore into journalissuearticles values(6.97 t/ha); and grain yield insert ignore into journalissuearticles values(6.32 t/ha); as compared to other treatments. Short term addition of rice straw in soil did not create any significant influence on post harvest soil nutrient status except K which was found high. Significantly highest N contents in grain and straw were observed in straw added plots, which further contributed to higher nutrient uptake by grain and straw.
