Abstract
A field experiment was conducted to study the effect of different high efficiency herbicides as pre- and post-emergence application on weed growth, yield and economics of groundnut at Tirupati campus of Acharya N.G. Ranga Agricultural University during Rabi, 2018. Among all the weed management practices, the broad-spectrum weed control with higher pod yield and benefit-cost ratio were obtained with pre-emergence application of diclosulam 20 g/ha followed by hand weeding at 40 DAS and next best option could be the pre-emergence application of diclosulam 20 g/ha followed by cycloxydim 100 g/ha at 20 DAS in sandy loam soils.
