Abstract:
A field experiment was conducted during two consecutive summer of 2020 and 2021 to investigation “Performance and economical evaluation of different weed management practices on yield of summer sesame (Sesamum indicum L.)” at agricultural farm of Krishi Vigyan Kendra, Durg-II (Chhattisgarh). The experiment treatments were include W₁: Weedy check, W₂: Hand weeding at 20 and 40 DAS, W₃: Pendimethaline 30 EC @ 1 kg ai ha^-1 as PE, W₄: Quizalofop ethyl 5 EC @ 40 g ai ha^-1 at 20 DAS, W₅: Propaquizafop 10 EC @ 50-100 g ai ha^-1 at 20 DAS, W₆: Imazethapyr 10 SL @ 75 g ai ha^-1 at 25 DAS and W₇: Weed free check. Among different weed management treatments, weed free check (W₇) recorded statistically lower density of total weeds during 2020 and 2021 than rest of the treatments at all the stages of observation. Second best treatment was W₂; two hand weedings at 20 and 40 DAS. Among all the herbicidal treatments, application of Propaquizafop recorded lower density of total weeds during both the years. The highest seed yield and stover yield was recorded in Weed free check, which was found at par with hand weeding at 20 and 40 DAS during both experimental year. Among all the herbicides, Propaquizafop and Quizalofop ethyl, recorded maximum yield, while Pendimethalin produced lower sesame yield. Highest cost of cultivation and gross return were found with the weed free check (W₇), followed by W₂; Hand weeding at 20 and 40 DAS, whereas maximum net return and benefit: cost ratio was observed in W₅ that is application of Propaquizafop 10 EC @ 50-100 g ai ha^-1 at 20 DAS. Minimum cost of cultivation, gross return, net return and benefit: cost ratio was associated with W₁ (weedy check).
