| Popis: | The field experiment was carried out during the period from July to November, 2013 at the research farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to investigate the influence of nitrogen and phosphorus on the growth and yield of BRRI dhan57. The two factorial experiments were laid out in a Randomized Complete Block Design (RCBD) with three replications. Four levels of nitrogen N 0 : 0 kg N ha -1 , N 1 : 90 kg N ha -1 , N 2 : 120 kg N ha -1 , N 3 : 150 kg N ha -1 and three levels of phosphorous P 0 : 0 kg P 2 O 5 ha -1 , P 1 : 25 kg P 2 O 5 ha -1 and P 2 : 35 kg P 2 O 5 ha -1 were used in this experiment. Data revealed that at 30 and 60 days after transplanting (DAT) and at the time of harvest the tallest plants were observed in the treatments N 2 (120 kg N ha -1 ), P 2 (35 kg P ha -1 ) and treatment combination N 2 P 2 (120 kg N and 35 kg P ha -1 ) whereas, the treatments N 0 , P 0 and treatment combination N 0 P 0 (without N and P) showed the smallest plant height in each case, respectively. Side by side, N 2 , P 2 treatments and N 2 P 2 treatment combination gave the maximum effective tillers hill -1 , highest length of panicle and the maximum filled grains panicle -1 . The highest 1000 grain weight (20.85 g), grain yield (4.95 t ha -1 ), straw yield (5.39 t ha -1 ) and biological yield (10.34 t ha -1 ) were found in the treatment combination N 2 P 2 and also found highest in each individual under N 2 and P 2 treatments. |
