Abstract: A field experiment was conducted with nine treatments (Weedy check, One hand weeding 30, DAS two hand weeding at 20 & 40 DAS, Pendimethalin (PE) @ 1.00 ai kg/ha, Oxyflorafen (PE) 0.20 ai kg/ha, Isoproturan (PE) 1.00 ai kg/ha, Pendimethalin (PE) @1.00 ai kg/ha+ Hand weeding at 30 DAS, Oxyflorafen (PE) 0.20 ai kg/ha + Hand weeding at 30 DAS, Isoproturan (PE) 1.00 ai kg/h + Hand weeding at 30 DAS) at Ayodhya during 2017-18. Among the different weed management practices maximum number of siliquae plant-1(248.73), Length of siliqua 6.70 cm, Number of seeds siliqua-1 12.01, Test weight 5g, Seed yield 2255 kg ha-1, Stover yield 6063 kgha-1,Harvest index 27.10 (%) Oil content 37.95(%), Oil yield 855.81 kg ha-1 under Two hand weeding at 20 & 40 DAS followed by treatment having Pendimethalin (PE) @ 1.00 ai kg/ha+ Hand weeding at 30 DAS, similarly maximun net return was obtained under Pendimethalin (PE) @ 1.0 kg ha-1 + hand weeding at 30 DAS (Rs. 72862 ha-1) followed by two hand weeding at 20 and 40 DAS (Rs. 71469 ha-1) while maximum gross return was recorded under two hand weeding at 20 and 40 DAS (Rs. 102326 ha-1) followed by Pendimethalin (PE) @ 1.0 kg ha-1 + hand weeding at 30 DAS (Rs. 99498 ha-1). Pendimethalin (PE) @ ai 1.0 kg ha-1 (2.76) resulted in highest net return per rupee invested on weed control.
