Abstract: A field experiment was carried out to evaluate the effect of different weed management practices on growth and yield of summer sesame (Sesamum indicum. L) during summer season of 2018 at Agricultural Farm of Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal. Eight weed management treatments namely- pendimethalin 750 g/ha at 1 DAS, butachlor 1000 g/ha at 3 DAS, pendimethalin 750 g/ha at 1 DAS fb 1 HW at 30 DAS, butachlor 1000 g/ha at 3 DAS fb 1 HW at 30 DAS, HW at 15 DAS, HW at 15 and 30 DAS, weed free check and weedy check were laid out in Randomized Block Design with three replications. The result revealed that integration of pendimethalin and butachlor each with one HW at 30 DAS recorded higher growth attributes, yield and yield components than their sole application. Although pendimethalin and butachlor fb one HW at 30 DAS registered higher gross return (₹82,687/ha and ₹76,405/ha, respectively) and net return ((₹56,825/ha and ₹51,067/ha, respectively) but the return per rupee invested was higher in their sole application (3.27 and 3.20, respectively). Based on overall performance, sole application of pendimethalin 750 g/ha at 1 DAS and butachlor 1000 g/ha at 3 DAS may be considered as promising cost-effective herbicides for improvement on seed yield in summer sesame.
