Castor crop weed free up to harvest recorded significantly lowest weed density and dry weight of weeds and maximum in seed yield which found statistically on par with the treatment weed free up to 120 DAS and weed free up to 90 DAS. However, treatment having weed free condition up to 90 days recorded maximum net return (70484) as well as B:C ratio (3.28) ascompared to all the treatments. Thus, to realize the potential monetary return and seed yield of castor with reducing the weed competition, crop should be kept weed free up to initial 90 days after sowing, which is more crucial for crop weed competition.
