Abstract: The investigation was conducted at experimental farm of Department of Agronomy, College of Agriculture, V.N.M.K.V., Parbhani (M.S), India during Kharif season of 2017-18 to evaluate performance herbicides in soybean. The experiment was laid down in randomized block design. The weed management treatments consisted of T1- Propaquizafop + Imazethapyr PoE @ 75+100 g a.i /ha, T2- Fluazifop-p-butyl + Fomesafen PoE @ 250 g a.i /ha, T3- Imazethapyr + Quizalofop ethyl PoE @ 100+75 g a.i/ha. (Tank mix), T4- Imazethapyr + Imazamox PoE @ 70 g a.i/ha, T5- Diclosulam PE @ 22 g a.i/ha, T6 - Haloxyfop + Imazethapyr PoE @ 50+100 g a.i/ha. (Tank mix), T7- Haloxyfop PoE @ 75 g a.i /ha, T8- Cultural practices (1HW + 1Hoeing), T9- Weed free, T10– Weedy check with the objectives to study the comparative performance of herbicide combinations in soybean. Among the different herbicides used, treatment Fluazifop-p-butyl + Fomesafen PoE @ 250 g a.i /ha recorded seed yield at par with weed free and recorded significantly higher seed yield over rest of treatments except it was statistically at par with cultural practices i.e. one Hand Weeding + one Hoeing and treatment Imazethapyr + Imazomox PoE @ 70 g a.i/ha. In weed studies, the lowest dry weight of monocot and dicot weeds was recorded with weed free and was at par with PoE application of Fluazifop-p-butyl + Fomesafen @ 250 g a.i /ha.
