Abstract: A field experiment was conducted to study the effect of different methods of weed management (herbicidal and chemical) in transplanted rice (Oryza sativa L.) during boro seasons of 2002-03 and 2003-04 at the Regional Research Sub-Station (RRS), Chakdaha, Nadia, We~t Bengal. The experiment was laid out in a Randomizd Block Design (RBD) having twelve treatments replicated thrice. The data revealed that weed free check produced significantly higher grain (5.10 t/ha) and straw yield (7.31 tlha) which, however, were statistically at par with two hand weedings at 20 and 40 DAT. (4.95 and 7.20 t/ha, respectively) and Bensulfuron-methyl + Butachlor@ 0.05 + 0.938 kg a.i./ha as PE (4.82 and 6.95 tlha, respectively). Phytotoxicity symptoms on rice crop were studied and it was observed that none of the herbicidal treatments showed any types of phytotoxic symptoms on rice crops at 1 to 10 days after application of herbicide. Pre-emergence application ofBensulfuron-methyl + Butachlor@ 0.05 + 0.938 kg a.i./ha proved beneficial for successful cultivation of paddy during boro season in the gangetic plains of West Bengal.
