OPTIMIZING FERTILIZER RATE FOR BANGLAMATI (BRRI dhan50) RICE IN EASTERN SURMA-KUSHIYARA FLOODPLAIN (Pages : 1 - 3)

An experiment was conducted at Satra village of Sadar Upazilla, Sylhet during November 2011 to May 2012 to investigate the effect of rate of fertilizers on the growth and yield of rice var. BRRI dhan50. The experiment consisted of nine treatments which were control (T1), 65-40-25-4.5-0.5 (T2), 97.5-60-35.5-6.75-0.75 (T3), 130-80-50-9-1 (T4), 162.5-100-62.5-11.25-1.25 (T5), 195-120-75-13.5-1.5 (T6), 227.5-140-87.5-15.75-1.75 (T7) as N-P-K-S-Zn kg ha-1, respectively, cow dung 20 t ha-1 (T8) and 75 kg N+10 kg P+20 kg K (T9). The experiment was laid out in a randomized complete block design with three replications. The results showed significant variations among the fertilizer doses for all the measured crop characters like plant height, number of panicles hill-1, length of panicle, number of spikelet panicle-1, percent unfilled grain, 1000-grain weight, grain yield, straw yield and harvest index. The highest grain yield (5.23 t ha-1) was recorded in treatment T4 (N-P-K-S-Zn: 130-80-50-9-1 kg ha-1). The treatment T3 and T8 produced 4.95 t ha-1 and 4.83 t ha-1 grain yields, respectively; and these are statistically similar to the treatment T4. On the other hand the lowest grain yield (3.07 t ha-1) was recorded in treatment T7. In fine application of fertilizer at the rate of N-P-K-S-Zn: 97.5-60-35.5-6.75-0.75 kg ha-1 would be recommended for maximum production of BRRI dhan50 rice in Sylhet region of Bangladesh.Download
