Abstract: A field experiment was conducted during 201415 and 201516 at Hisar, Haryana, to study bioefficacy of metribuzin-based herbicide mixture on weeds and producitivty of wheat (Triticum aestivum L.). The experiment was conducted in a split-plot design comprising 5 wheat varieties WH 1105, HD 2967, DPW 621-50, WH 1124 and DBW 17 in main plots and 6 weed-management practices, viz. metribuzin (210 g/ha), metribuzin + fenoxaprop (150 + 100 g/ha), metribuzin + pinoxaden (150 + 40 g/ha) metribuzin + clodinafop (150 + 45 g/ha), weed-free and weedy check, in subplots, each replicated thrice. The wheat varieties did not affect the weed den- sity and weed dry-matter accumulation. Wheat variety WH 1105 resulted in the maximum grain, straw and biologi- cal yields, being statistically at par with HD 2967 and DPW 621-50, but significantly better over DBW 17 and WH 1124. Among the herbicides, the density of grassy and total weeds and their dry-matter accumulation at all stages were observed minimum with metribuzin + fenoxaprop which remained at par with other 2 combinations of metribuzin, whereas density and dry matter of broad-leaf weeds were found minimum with metribuzin alone (210 g/ha). Alone application of metribuzin resulted in the lowest grain yield of wheat as compared to all the other herbi- cidal treatments.
