Abstract: Soybean (Glycine max L. Merrill) is one of the commercial crops in India. It grown as kharif crop, but weed infestation is the major constraint in soybean produce in rainy season A field experiment was conducted at Research farm, Department of Agronomy, Jawaharlal Nehru Kirshi Vishwa Vidyalaya, Jabalpur (M.P.) during kharif 2016 to evaluate the bio-efficacy of post emergence herbicides against weed control in soybean. Among all herbicidal treatment the post emergence application of Imazethapyr+Propaquizafop 75.0+62.5 g/ha recorded highest number of pods/plant (26.10), higher number of seed/pod (2.40), 100 seed weight (9.93), seed yield (2100 kg/ha), haulm yield (3900 kg/ha), net returns (26585 Rs/ha) and B:C ratio (1.75), which was comparable with the application of Imazethapyr + Bentazone 75+75 g/ha.
Keywords: Herbicide, Benefit cost ratio, net return, weed control efficiency
