Abstract

An experiment was conducted to study the yield components and yield of Boro rice (cv. BRRI dhan63) under different nutrient and weed management strategies. The experiment was laid out in a two factor randomized complete block design with three replications consisting of four nutrient management strategies viz. cowdung 10 t ha-1, recommended dose of chemical fertilizer (urea, triple super phosphate, muriate of potash, gypsum and zinc sulphate @ 258, 101, 120, 113 and 11.5 kg ha-1, respectively), 75% recommended dose of chemical fertilizer + cowdung 5 t ha-1 and 50% recommended dose of chemical fertilizer + cowdung 10 t ha-1; and five weed management strategies viz. weedy check, hand weeding twice at 15 and 30 days after transplanting (DAT), pre-emergence herbicide Panida at 3 DAT, post-emergence herbicide Granite at 10 DAT and Panida at 3 DAT + Granite at 10 DAT. Yield components and yield of Boro rice cv. BRRI dhan63 were significantly influenced by nutrient and weed management strategies. Application of 75% recommended dose of chemical fertilizer + cowdung 5 t ha-1 showed the highest values for all yield components and produced the highest grain yield (6.24 t ha-1) while among the weed management strategies, Panida at 3 DAT + Granite at 10 DAT produced the highest grain yield (6.39 t ha-1) and the interaction of this two treatments also produced the highest grain yield (6.97 t ha-1). Among the different nutrient management strategies, cowdung 10 t ha-1 produced the lowest values of most of the yield contributing characters and grain yield (4.92 t ha-1) while in case of weed management strategies weedy check produced the lowest grain yield (4.55 t ha-1) and the interaction of this two treatments also produced the lowest grain yield (4.05 t ha-1). Therefore, it can be concluded that 75% recommended dose of chemical fertilizer + cowdung 5 t ha-1 combined with Panida at 3 DAT + Granite at 10 DAT can be practiced for the cultivation of Boro rice cv. BRRI dhan63 to obtain the highest grain yield.

Key words: Cowdung, Granite, Herbicide, Panida, Post-emergence, Pre-emergence
