Abstract:
A field experiment was carried out at Research Farm, Department of Agronomy, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) during rabi season 2016-17 and 2017-8, on effect of post emergence herbicides on yield and economics of wheat. Twelve herbicide treatments comprised of post emergence application of Halauxifen – methyl 6.95% + Pyroxsulam 25% with and without surfactant at different doses and compared with alone application of Halauxifen-methyl 10.42% with surfactant, Pyroxsulam 4.5% with surfactant, Sulfosulfuron + Metsulfuron – methyl with surfactant and untreated plot (weedy check plot). The experiment was laid out in randomized block design with thrice replication. The experimental results revealed that Maximum grain yield (4818 kg ha^-1), straw yield (6561 kg ha^-1), gross monetary returns (96718 Rs. ha^-1), net Monetary returns (68695 Rs. ha^-1) and benefit cost ratio (3.09) were recorded under application of Halauxifen-methyl 6.95% + Pyroxsulam 25% + Surfactant at 23.96 a.i. g ha^-1 as compared to rest of the treatments.
