Abstract


A field experiment was conducted during 2010-11 and 2011-12 at Oilseed Research Station, Mamurabad farm, Jalgaon (M.S.) to assess critical period of crop-weed competition and find out ideal weeding time for rain fed sesamum. The results revealed that, 15 to 30 DAS were more crucial and critical period for crop-weed competition. Minimum loss (16.71%) was observed with weeding at 30 DAS and produced significantly more yield (553kg ha-1) than weeding at 45 and 60 DAS . It also increased net monetary return (Rs 14332 ha-1) and B:C ratio (1.86) which indicated that, hand weeding at 30 DAS economically more feasible than other growth stages for rainfed sesamum in the region
