Abstract:
The field investigation entitled on efficacy of broad spectrum post emergence herbicide combinations in soybean (Glycine max (L.) Merrill)” was conducted during kharif 2021-22 at experimental farm, Department of Agronomy, College of Agriculture, VNMKV, Parbhani (M.S) with a view to study the effect of different broad spectrum post emergence herbicides on weed control in soybean as well as growth and yield of soybean. The experiment was laid out in Randomized Block Design. The experiment was carried out with seven weed management practices each treatment was replicated thrice. Treatment were T1-PoE- Fluazifop-p-butyl 11.1% + Fomesafen 11.1% W/W SL @ 250 g a.i ha-1, T2- PoE- Imazethapyr 35% + Imazamox 35% WG @ 70 g a.i ha-1, T3- PoE- Sodium acifluorfen 16.5% + clodinafop propargyl 8% EC @ 80 +165 g a.i ha-1, T4- PoE- Propaquizafop 2.5% + Imazethapyr 3.75% W/W @ 50 + 75 g a.i ha-1, T5- PoE- Fomesafen 12% + Quizalofop ethyl 3% SC @ 180 +45 g a.i ha-1, T6- Weed free and T7- Weedy check. Results of study revealed that among the herbicide combinations the lowest weed count for both monocot and dicot weed and highest seed yield, as well as net monetary returns were recorded with post emergence application of Fomesafen 12% + Quizalofop ethyl 3% SC @ 180 +45 g a.i ha-1 (T5), PoE-Fluazifop-p-butyl 11.1% + Fomesafen 11.1% W/W SL@ 250 g a.i ha-1 (T1) and PoE- Sodium acifluorfen 16.5% + clodinafop propargyl 8% EC @ 80 +165 g a.i ha-1 (T3). These treatments were comparable to weed free (T6) and found to be significantly superior over rest of treatments of post emergence herbicide combinations for weed control in soybean.
