ResumoA field experiment was conducted during kharif season of 2017 and 2018 at Agriculture Research Sub Station, Kotputli, Jaipur, where four herbicides either as integrated with hand weeding or sequentially applied were evaluated for efficacies of the herbicides on controlling weeds, their influences on green pod yield of vegetable cluster bean in randomized block design with four replications.The results of two-year experimentation indicated that all the weed control treatment gave significantly minimum dry weight of weed and higher green pod yield over no weeding.In pooled data based on both the years, the treatment of weed free check was found highest value of green pod yield (44.53 q/ha).It was found at par with two hand weeding at 20 and 40 DAS(44.06q/ha), Pendimethalin @ 1.0 kg ai./ha as pre-emergence & one hand weeding at 25 DAS (43.41 q/ha) and Imazathyper 10 SL@ 40 g ai./ha at 15-20 DAS (42.98 q/ha).Highest weed control efficiency and minimum weed index were observed in weed free check.Among various herbicides treatments, Imazathyper 10 SL@ 40 g ai./ha at 15-20 DAS showed highest B:C ratio in both the years and it was significant differ over the rest of treatments.In monetary term imazathyper 10 SL@ 40 g ai./ha recorded higher net return (Rs.85948/ha) and benefit: cost ratio (3.0) over weed free check (Rs.79590/ha and 2.47, respectively) K e y w o r d s
