The field experiments entitled “Economic feasibility of wheat cultivation under different herbicides doses at Dehradun Condition” was conducted during Rabi season of 2021-22 at the SIPS, Dehradun to obtain the information on relative performance on wheat crop and weeds under different herbicides. The experiment consisted of 11 treatments i.e. Pendimethalin (pre-emergence) @ 1lit ai. ha^-1, Pyroxasulfone (pre-emergence) @ 127.5g ai. ha^-1, Metsulfuron (post-emergence) @ 4g ai. ha^-1, Sulfosulfuron (post-emergence) @ 25g ai. ha^-1, Pendimethalin (1lit ai. ha^-1) fb Sulfosulfuron (25g ai. ha^-1), Pendimethalin (1lit ai. ha^-1) fb Metsulfuron (4g ai. ha^-1), Pyroxasulfone (127.5g ai. ha^-1) fb Metsulfuron (4g ai. ha^-1), Pyroxasulfone (127.5g ai. ha^-1) fb Sulfosulfuron (25g ai. ha^-1), Sulfosulfuron (25g ai. ha^-1) + Metsulfuron (4g ai. ha^-1), Weed free and Weed check was laid out in Randomized block design with three replications. It concluded that highest grain yield (50 q ha^-1) recorded under weed free treatment which was at par with Sulfosulfuron (25g ai. ha^-1) + Metsulfuron (4g ai. ha^-1), Pyroxasulfone (127.5g ai. ha^-1) fb Sulfosulfuron (25g ai. ha^-1), Pendimethalin (1lit ai. ha^-1) fb Sulfosulfuron (25g ai. ha^-1) and Sulfosulfuron (post-emergence) 25g ai. ha^-1 while significantly higher than rest of treatments. It concluded that highest straw yield (70.20 q ha^-1) recorded under weed free treatment. Maximum cost of cultivation (Rs. 57911 ha^-1) found with weed free treatment whereas minimum under the weedy check treatment. Higher gross return (Rs.141770.50 ha^-1) and net return (Rs. 87947.00 ha^-1) recorded under weed free treatment. Whereas highest B: C (1:2.80) ratio recorded under Sulfosulfuron (25g ai. ha^-1) + Metsulfuron (4g ai. ha^-1). Thus Sulfosulfuron (25g ai. ha^-1) + Metsulfuron (4g ai. ha^-1) may be recommended for better weed control, higher wheat yield and profit.
