ABSTRACT
Six varieties namely IR-6, IR-9, KS-282, Bas-370, Bas-198 and Bas-385 were sown at seed rate of 100 kg ha-1.Two herbicides viz. Acelor @ 250 ml ha-1 and Rifit @ 1 l ha-1 were applied as post emergence (30 days after seeding) to all plots except weedy check (control). Weeds were affectively controlled with herbicides application. Maximum number of tillers m-2 (340.2), number of panicles m-2 (329.8), 1000-grain weight (25.50 g), highest paddy yield (7.50 t ha-1) and straw yield (19.24 t ha-1) were observed in KS-282. Acelor @ 250 ml ha-1 controlled weeds more effectively and gave minimum weed population m-2 (15.28), maximum number of tillers m-2 (330.7), number of panicles m-2 (319.0), number of spikelets per panicle (139.2), 1000-grain weight (21.99 g), paddy yield (6.48 t ha-1) and harvest index (31.39 %).
