Title: Efficacy of metsulfuron methyl for controlling broadleaf weeds in transplanted rice (Oryza sativa) under rainfed shallow lowland.
Abstract: All the herbicidal treatments were significantly superior to weedy check. There was more than 44% reduction in the grain yield of rice due to competition with weeds in the weedy plots. The highest grain yield (4.96 tonnes/ha) and N-use efficiency (62.0) were obtained in weed-free check. Among the tested herbicides, metsulfuron methyl 8 g/ha applied 10 days after transplanting was found to be the most effective herbicide (weed control efficiency 87.9%) in controlling the pre-dominant weeds, and thereby realizing an increase of 72% yield over weedy check. It was comparable with weed-free check. The N-use efficiency (59.8) was also higher in metsulfuron methyl (8 g/ha), followed by tank-mix application of metsulfuron methyl + chlorimuron ethyl at 4 +6 g/ha (57.9) and chlorimuron ethyl at 8 g/ha (55.8).
