An experiment was conducted at Research Farm of CCS Haryana Agricultural University, Hisar Haryana (India) during 2014-15 and 2015-16, to study the influence of varieties and herbicide mixtures on wheat in relation to phytotoxicity and residual soil nutrients. The treatments consisting of five varieties of wheat viz., WH 1105, HD 2967, DPW 621-50, WH 1124 and DBW 17 in main plots and six weed management practices i.e. metribuzin (210 g ha-1), metribuzin+fenoxaprop (150+100 g ha-1), metribuzin+pinoxaden (150+40 g ha-1), metribuzin+clodinafop (150+45 g ha-1), weed free and weedy check in sub-plots in split plot design with three replications. All the herbicide treatments were applied at 35 days after sowing (DAS) of wheat. No phytotoxic effect of any of the herbicidal treatments was observed on crop during both years except appearance of some spots on leaves of wheat variety HD 2967 after spray in plots treated with metribuzin alone and tank mix application of metribuzin + fenoxaprop, which didn’t show any effect on yield of the crop. There was no significant effect of weed management practices on residual organic carbon (%), available P2O5, and K2O during both the years, however, available soil N after crop harvest was significantly lower in weed free plots as compared to all the herbicides treated and weed free plots during both the years.
