abstract
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.
