Field experiment conducted at College of Agriculture, Rewa, Madhya Pradesh revealed that plant height, number of tillers/m2, leaf area index (LAI), dry matter accumulation (DMA) in plants, Crop growth rate (CGR) and net assimilatory rate (NAR) were higher in plots getting hand weeding twice and with application of 125 kg N/ ha (N3) as compared to lower levels of nitrogen application and other weed management practices, whereas, application of butachlor + dhaincha (1:1) + 1 hand weeding had comparatively surpassed other weed management practices. Similarly, yield attributes were significantly higher in hand weeding twice with application of butachlor + dhaincha (1:1) + 1 hand weeding. Highest (1.77) net B:C ratio was captured with application of butachlor + dhaincha (1:1) + 1 hand weeding  and lowest (0.87) under weedy check.
