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.

to assess the effect of different sources of nutrients on growth, yield, residual nitrogen status and physiology of black gram. The treatment combinations include T1:

The experiment comprised of five post emergence herbicides (metsulfuron, carfentrazone, 2, 4-D Ester, pyroxsulam and halauxifen) and their mixtures at different doses along with weedy check and weed free treatment. Major weed flora in experiment includes Anagallis arvensis, Chenopodium album, Melilotus indicus, Medicago denticulata, Rumex dentatus etc. Application of the herbicides halauxifen + pyroxsulam at 23.96 g/ha, metsulfuron + 2, 4-D Ester at (3 + 500 g/ha) and halauxifen + pyroxsulam at 19.17 g/ha significantly increased the dry matter accumulation of wheat and plant height at harvest compared to weedy check. Application of halauxifen + pyroxsulam at 23.96 kg/ha, metsulfuron + 2, 4-D Ester at 3 + 500 g/ha and carfentrazone + 2, 4-D Ester at 15 + 500 g/ha resulted into higher number of tillers per meter row length. Application of halauxifen + pyroxsulam sprayed at 23.96 g/ha at 35 days after sowing was the most effective treatment to control the weeds in wheat with higher grain yield of 5395 kg/ha, straw yield of 8466 kg/ha and biological yield of 13861 kg/ha with highest weed control efficiency followed by metsulfuron + 2, 4-D Ester at 3 + 500 g/ha and carfentrazone + 2, 4-D Ester at 15 + 500 g/ha.
