Abstract:
A field experiment was conducted at Agricultural Research Station, Ummedganj, Kota during kharif, 2019 to study of comparative efficacy of herbicidal weed management practices in soybean (Glycine max L. Merrill). The ultimate aim of any soybean grower is to secure maximum net income out of the present production technology. Two hand weeding at 20 and 40 DAS gave significantly higher seed yield over herbicidal weed control. In the investigation maximum net return was fetched with hand weeding twice at 20 and 40 DAS (₹ 39571 ha^-1) closely followed by application of Sodium acifluorfen 16.5% + Clodinafop propargyl 8% EC (premix) @ 165 + 80 g a.i. ha^-1 at 20 DAS (₹ 38204 ha^-1). The benefit: cost ratio represents the profitability of the treatment with each rupee of investment. The benefit: cost ratio was highest recorded with application of Sodium acifluorfen 16.5% + Clodinafop propargyl 8% EC (premix) @ 165 + 80 g a.i. ha^-1 at 20 DAS was found more remunerative (1.61) than other herbicidal treatments including hand weeding (1.22).
