A field experiment was conducted at agronomy research farm of Acharya Narendra Deva University & technology, Kumarganj, Ayodhya (U.P.) during Rabi season (2021-22). The experiment was laid out in randomized block design with three replications. There were ten treatments i.e. T1 Clodinafop @ 60 g a.i. ha-1, T2 Sulfosulfuron @ 25 g a.i. ha-1, T3 Metsulfuron @ 4 g a.i. ha-1, T4 Carfentrazone ethyl @ 20 g a.i. ha-1 and tank mixture of T5 Clodinafop + Metsulfuron @ (60+4) 64 g a.i. ha-1, T6 Clodinafop + Carfentrazone @ (60+20) 80 g a.i. ha-1, T7 Sulfosulfuron + Metsulfuron @ (30+2) 32 g a.i. ha-1, T8 Sulfosulfuron + Carfentrazone (25+20) 45g a.i. ha-1, T9 Weed free were evaluated against mixed weed flora in wheat except and T10 Weedy check. The result revealed that all the growth parameters, yield attributes and yield of wheat is obtained significantly higher under T9 weed free treatment but statistically at par with T7 Sulfosulfuron + Metsulfuron @ (30+2) 32 g a.i. ha-1, T5 Clodinafop + Metsulfuron @ (60+4) 64 g a.i. ha-1, T6 Clodinafop + Carfentrazone (60+20) 80 g a.i. ha-1, T8 Sulfosulfuron + Carfentrazone (25+20) 45g a.i. ha-1. The highest net return (81054.50 Rs. ha-1) and benefit cost ratio (2.04) was recorded under Sulfosulfuron + Metsulfuron @ (30+2) 32 g a.i. ha-1, It was close to Clodinafop + Metsulfuron @ (60+4) 64 g a.i. ha-1. Thus, it may be recommended for highest yield of wheat and net return.
