Response of Sesame to Different Weed Management Pratices in Maharashtra, India

Abstract

The experiment was conducted at Agricultural Research Station, Jalgaon, Maharashtra during Kharif season of 2018 to 2020 to study the effect of pre and post emergence herbicide on growth and yield of sesame. The experiment was laid out in a Randomized Block Design (RBD), replicated thrice with eight treatments viz., T1 Weedy check, T2 Weed free, T3 Pendimethalin 30EC (pre–emergence)@0.50kg a.i./ha., T4 Quizlofop-ethyl 5 % EC (post emergence) 50g a.i/ha.at 20 DAS., T5 Sodium Acifluorfen16.5% + Clodinafop-propargyl 8% (premix) @ 100 g.a.i./ha.at 20 DAS., T6 Pendimethalin 30EC (pre–emergence)@ 0. 50 kg a.i./ha.+ Hand weeding at 20DAS., T7 Pendimethalin 30EC (pre–emergence)@0. 50 kg a.i./ha.+ Quizlofop-ethyl 5 % EC (post emergence) 50g a.i/ha.at 20 DAS., T8 Pendimethalin 30EC (pre–emergence) @ 0. 50 kg a.i./ha.+ Sodium Acifluorfen16.5% +Clodinafop-propargyl 8% (premix) @ 100 g.a.i./ha. at 20 DAS.From the pooled results,it is concluded that pre and post emergance herbicide for chemical weed management in sesame, the seed yield were found to be significant.The practice of the treatment T2 (weed free) crop produced the significantly highest seed yield 607 Kg./ha, Net Monetory Returns Rs. 42730/- and B:C Ratio 2.93, over rest of treatment, followed by 523 kg/ha seed yield, Rs. 35873/- Net Monetory Returns and 2.77 B:C ratio by the treatment i.e. pre–emergence application of Pendamethalin 30 EC @ 0. 50 kg a.i./ha + Hand weeding at 20 DAS was an efficient and economically feasible package to manage the weeds and realize better returns.
