A field experiment was conducted during Kharif 2017 to study the effect of different weed management practices on diverse weed flora and yield of green gram at College of Agriculture, Gwalior, India. An experiment was replicated thrice in a randomized complete block design and consisted of 10 treatments as white plastic mulch, black plastic mulch, straw mulching 5 days after sowing (DAS) @ 5 t/ha, one hand weeding at 20 DAS + straw mulching at 25 DAS, two hand hoeing at 20 & 40 DAS, two hand weeding at 20 & 40 DAS, hand weeding at 20 DAS + hoeing at 40 DAS, recommended herbicide (Imazethapyr @ 80 g/ha) + one hand weeding at 40 DAS and weedy check. The highest mortality of weeds, weed control efficiency (94.1%) and maximum grain yield (824 kg/ha) with 104.0% increase in grain yield over weedy check were recorded with one hand weeding at 20 DAS conjointly with straw mulching at 25 DAS. Whereas, the highest B:C ratio of (2.52) was obtained with Imazethapyr 80g/ha as PE followed by application of Imazethapyr 80g/ha with one hand weeding at 40 DAS (2.08).
