Application of Oxyfluorfen 23.5 EC @ 0.2kg ha-1 at 2 DAS fb Imazethapyr 10 percent SL @ 100 g ha-1 at 15 DAS recorded higher pod yield (22.7/ha), maximum weed control efficiency (80.92, 76.39 and 75.10% at 20, 40 and 60 DAS respectively) and with maximum net return (71309 Rs/ha) and BCR (2.79) which were higher than farmers practices of one hoeing at 21 DAS. The demonstrated practice was proved practically more convenient and economically best feasible weed management practice for groundnut considering the present condition of scarcity and high cost of labours, quality of weed control, yield and B:C ratio of cultivation of rabi Groundnut.
