Abstract
A field study was conducted to investigate the effect of different NP levels i.e., 0-0, 25-0, 50-25, 75-50, 100-75 and 125-100 kg ha'1 on yield and yield attributes of rice Bas-385. Yield attributes (No. of effective tillers per hill, spikelets per panicle, normal kernels per panicle, 1000-grain weight) were improved linearly with increasing NP levels up to 100-75 kg/ha. The NP level of 100-75 kg ha" resulted in the highest grain yield of 4.53 t ha" with minimum kernel abnormalities (Sterility, abortive kernels and opaque kernels) as against the minimum of 2.356 t ha" in the control (0-0) followed by 25-0 kg NP ha' with maximum kernel abnormalities.
