Abstract
Study revealed that drum seeding + green manure method of seedling establishment and pre-emergence application of pretilachlor + safener at the rate of 0.45 kg/ha on 5 days after sowing (DAS) fb hand weeding (HW) at 45 DAS registered lowest weed density, weed biomass, highest weed control efficiency (WCE), zero per cent weed index (WI), lowest depletion of NPK nutrient by weeds and highest grain yield of crop and B: C ratio
