Abstract:
During the Kharif season of 2020, a field study was under taken at the College of Agriculture, AU, Kota, Rajasthan, to investigate the nutrient depletion by weeds and economic parameters of various weed management strategies, including alone and ready-mix herbicides in urdbean [Vigna mungo (L.) Hepper]. Two hand weeding at 20 and 40 DAS reduced the nutrient depletion and weed dry matter significantly as compared to weedy check and was almost at par pendimethalin 30% EC @ 1 kg ha-1(PE) propaquizafop fb 2.5%w w-1@ 33.3 g ha-1+ imazethapyr 3.75% w w-1 (pre mix) ME @ 50 g ha-1 at 20 DAS. The two hand weeding at 20 and 40 DAS showed its superiority and reflected in net return ₹ 16030 ha-1 and B-C ratio 0.49. Among herbicide management practices, the treatment pendimethalin 30% EC @ 1 kg ha-1(PE) propaquizafop fb 2.5%w w-1@ 33.3 g ha-1+ imazethapyr 3.75% w w-1 (pre mix) ME @ 50 g ha-1 at 20 DAS significantly recorded lowest weed dry matter at harvest and nutrient depletion by weeds, as well as the highest net return and B:C ratio among herbicidal weed control treatments.
