Abstract

A field experiment was undertaken to evaluate the performance of different weed control treatments in cluster bean during kharif, 2015 in RBD with three replications. Treatment of weed free check was found best by recording highest values of yield attributes, seed (20.97 q/ha), stover (65.68q/ha) with maximum weed control efficiency at successive stages. Among different herbicides treatments, Imazethapyr + Imazamox @ 40 g/ha (PoE) at 20 DAS showed highest values of yield attributes, seed yield (19.59 q/ ha), stover yield (63.83 q/ ha), WCE (91.84, at 60 DAS) and minimum WI (6.0). In monetary terms significantly highest net return (Rs.86883 /ha) were obtained from weed free check, followed by imazethapyr + imazamox @ 40 g/ha (PoE) at 20 DAS (Rs.85398 / ha) and imazethapyr @ 75 g/ha (PoE), at 20 DAS (84394 Rs./ha). The maximum B:C ratio of 6.57 was recorded with treatment imazethapyr @ 75 g/ha (PoE), followed by imazethapyr+ imazamox @ 40 g/ha (PoE) 6.37.
