Abstract: A field experiment was conducted to evaluate performance of different herbicides in wheat crop on heavy soil at Crop Research Centre, Chirodi form of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) during Rabi season 2016-17. The experiment was conducted in randomized block design with three replications comperising 12 treatments of weed management were Pendimethalin @ 750gai ha-1 fb1HW (T1), Pendimethalin fb Sulfosulfuron @ 750+15g ai ha-1 (T2), Sulfosulfuron @25gai ha-1 (T3), Sulfosulfuron+Metsulfuron-methyl @ 20+2 g ai ha-1 (T4), Clodinofoppropazil @ 60 g ai ha-1 (T5), Clodinafop+Metsulfuron-methyl@ 60+4 g ai ha-1 (T6), Pinoxaden+Metsulfuron-methyl @ 40+4 g ai ha-1 (T7), Pinoxaden+Carfentarazone-ethyl @ 40+20 g ai ha-1 (T8), Metsulfuron-methyl+Iodosulfuron @ 12+24 g ai ha-1 (T9), Isoproturon+24-D @ 750+500 g ai ha-1 (T10), Weed free (T11) and Weedy check (T12). The soil of experimental site was low in organic carbon and nitrogen and medium in available phosphorus and available potassium and alkaline in reaction. The findings of present study revealed that all weed control practices were proved effective to control weeds in wheat crop and produced significantly higher grain yield over all weedy check. Whereas these treatments were also produced significantly higher grain yield than other treatments. Thus the application of Clodinafop+Metsulfuron-methyl @ 60+4 g a.i ha-1 as post emergence is concluded the best for effective weed control, higher productivity and profitability of wheat crop.
