Abstract:
The current investigation was done to evaluate the sequential application of herbicides on yield and economics of groundnut during rabi season, 2020-2021 at S. V. Agricultural College, Tirupati, Andhra Pradesh. Pendimethalin + Imazethapyr (Valor), Diclosulam, Alachlor, Bentazone, Imazethapyr, Quizalofop-p-ethyl were tested alone as well as in sequential application in comparison with hand weeding twice at 20 and 40 DAS and weedy check in randomized block design with three replications. This study revealed that among chemical treatments higher pod yield, net returns and BC ratio of rabi groundnut recorded with sequential application of diclosulam 20 g ha^-1 fb quizalofop-p-ethyl 50 g ha^-1 + bentazone 960 g ha^-1at 20 DAS (T₈) and alachlor 1250 g ha^-1 as pre-emergence fb quizalofop-p-ethyl 50 g ha^­-1 + bentazone 960 g ha^-1, (T₅) both were comparable with hand weeding twice which realised higher pod yield and gross returns.
