An experiment was conducted in the Rabi season of two consecutive years of 2019-20 and 2020-21, respectively to determine find out practically convenient and economic weed control measure for the onion growers. Treatments comprised T1 Farmers’ practice (pendimethalin 30% EC 1 kg ai/ha before transplanting+ 1HW at 25 DAT) and T2 (oxyflurofen 23.5% EC @ 0.10 kg ai/ha + quizalofop ethyl 5% EC @ 0.05 kg ai/ha at 25 DAT + 1 HW at 45 DAT) replicated at ten farmers’ field. Treatment T2 (oxyflurofen 23.5% EC @ 0.10 kg ai/ha + quizalofop ethyl 5% EC @ 0.05 kg ai/ha at 25 DAT + 1 HW at 45 DAT) recorded significantly lowest weed density (32.59/m2), highest plant height (52.50 cm), neck thickness (1.12 cm),bulb diameter (6.38 cm), bulb weight (92.57 g) and bulb yield (304.85 q/ha) as compared to treatment T1. The highest net returns (Rs 2,04,391/ha) and B:C (3.04) were obtained with T2.
