Abstract: A field experiment conducted during the kharif season of 1999 showed that hand weeding twice at 20 and 40 DAT resulted the lowest weed dry matter of 2.87, 5.85 and 10.91 g/m2 at 30, 60 and 90 DAT respectively which were at par with the treatment Anilofos + Ethoxy sulfuron at 390 g a.i./ha (Ready-mix). The highest WCE (92.55%) was obtained at 90 DAT with hand weeding treatment which was closely followed by the treatment Anilofos + Ethoxy sulfuron at 390 g a.i./ha. Number of effective tillers/m2 and number of filled grains/panicle differed significantly. The highest rice grain yield (4.48 Uha) was obtained with the hand weeding twice treatment which however, was at par with ready-mix herbicide mixture Anilpfos + Ethoxy sulfuron at 390 g a.i./ha yielding 4.42 Uha. Among all the herbicides tested, the ready-mix herbicide mixture Anilofos + Ethoxy sulfuron at 390 g a.i./ha applied 10 DAT proved to be the best for controlling all categories of weeds resulting the highest grain yield of rice.
