A field experiment conducted during the kharif season of 2000 showed that hand weeding twice at 20 and 40 DAT resulted the lowest weed dry matter of 6.9, 11.5 and 10.2 g/m2 at 30, 60 and 9O DAT respectively which were at par with the treatment Chlorimuron ethyl at 4, 6 and g g a.i./hectare. The highest WCE (62%) was obtained at 90 DAT with hand weeding treatment which was closely followed by the treatment Chlorimuron ethyl at 4, 6 and 8 g ai/hectare. Number of effective tillers/m2 and number of filled grain/panicle differed significantly. The highest rice grain yield (3.24t/hectare) was obtained with the hand weeding (twice) treatment which however was at par with the treatments Chlorimuron ethyl at 4, 6 and 8 g a.i./hectare yielding 3.07, 2.99 and 3.05 t/hectare respectively. Among all the herbicides tested, Chlorimuron ethyl at 4 g a.i./hectare applied 3 DAT proved to be the best for controlling all categories of weeds resulting the highest grain yield of rice in the southern plains of West Bengal.
