Abstract
Field experiments were conducted during winter, 2018-19 and summer, 2019 in groundnut and fodder sorghum, respectively at S.V. Agricultural College, Tirupati, Andhra Pradesh, India to know the performance of pre-emergence (pendimethalin 38.7% CS 725 g/ha and diclosulam 84% WDG 20 g/ha) and postemergence (haloxyfop-p-ethyl 10.5% EC 135 g/ha and cycloxydim 20% EC 100 g/ ha) herbicides on weed growth and yield of groundnut and their carryover effect on fodder sorghum. Significantly lower density and dry weight of weeds with higher WCE were recorded with pre-emergence application of diclosulam 20 g/ha + HW at 40 DAS and it was closely followed by pre-emergence application of diclosulam 20 g/ha fb cycloxydim 100 g/ha applied at 20 DAS in groundnut. The highest pod yield and benefit-cost ratio were registered with former weed management practice. All the herbicides tried did not show any inhibitory effect on germination, growth parameters and dry fodder yield of residual crop of fodder sorghum. Pre-emergence application of diclosulam 20 g/ ha fb cycloxydim 100 g/ha applied at 20 DAS in groundnut showed its superiority in supressing weed growth at early stages of fodder sorghum due to extended herbicidal activity of diclosulam and reduced weed seed bank.
