A field experiment "Efficacy of different herbicides in cluster bean" was conducted during the kharif seasons of 2018 and 2019 at Research Farm of RRS, Rohtak. Major weed flora in experiment includes Trianthema portulacastrum, Digera arvensis, Echinochloa colona, Amaranthus viridies etc. The season long growth of weeds reduced cluster bean yield up to 43.4 % and 44.6% during 2018 and 2019, respectively as compared to weed free condition. Sequential application of clethodium 120 g/ha 4 WAS resulted into significantly higher visual weed control and better crop yield as compared to alone application of pendimethalin 1000 g/ha PRE, whereas alone application of imazethapyr 70 g/ha PRE and imazethapyr + imazamox (RM) 70 g/ha PRE remained at par with it including weed free conditions during both the years of study. Thus, alone application of imazethapyr 70 g/ha PRE and imazethapyr + imazamox (RM) 70 g/ha PRE may be more economical and suitable for getting higher weed control and cluster bean yield avoiding one more application of herbicides as sequential application.
