Abstract:
A field experiment was conducted during rabi season of 2021-22 at Instructional-cum-Research Farm, IGKV, Raipur. The soil of experimental site was clayey, low in available nitrogen, medium in available phosphorus and potassium. The experimental design was Randomized Block Design (RBD) having 12 weed management treatments and three replications.The results showed that significantly higher growth characters, yield attributes, seed yield, stover yield and harvest indexwere obtained under metribuzin fb topramezone 350 and 32.25g ha^-1, but it was at par with metribuzin fb topramezone 350 and 25.8 g ha^-1 and hand weeding twice. The minimum values ​​of above character were observed under unweeded control plot. The treatment metribuzin fb topramezone 350 and 37.8 g ha^-1 were effective in reducing weed density, weed dry matter accumulation, lowest weed growth rate and therefore providing maximum weed control efficiency. While, weed index were higher control and lower in metribuzin fb topramezone 350 and 32.25 g ha^-1.
