A field experiment was conducted during rabi season of 2019-20 at College Farm, S. D. Agricultural University, Jagudan. The treatments included of best combinations consisting of physical and chemical methods as well as alone. The studies signified the importance of hand weeding at 25 and 40 DAS or application of post emergence herbicides which could benefit the crops in reducing the different weed density and ultimately reduced the weed dry matter which resulted in increase in the crop yield. Keeping the crop weed free up tharvest recorded higher weed control efficiency (100%) and lower weed index (0%). Higher growth and yield attributes under physical method alone and their integration with herbicide treatments might be due to effective control of weeds, significantly reduced crop–weed competition resulting in better congenial condition for growth and development of the crop. The maximum seed yield was recorded with weed free up to harvest and was at par with the treatments in which adoption of physical and chemical methods alone and their combinations. The maximum net realization and benefit cost ratio (BCR) were recorded with treatment T2 i.e. Two interculture followed by hand weed at 25 and 40 DAS.
