Abstract

Aim: This research work was conducted to study the response of wheat varieties and herbicide mixtures on weed suppression as well as growth and yield of wheat.

Methodology: An experiment was conducted in a split-plot design, in which the main plot comprised of three wheat varieties (HD 2967, DBW 187 and SS 303), and the subplots factor consisted of three herbicide mixtures, i.e., pendimethalin + pyroxasulfone (1000 + 125 g a.i. ha^-1), clodinafop-propargyl (CP) + metsulfuron-methyl (59.3 + 39.53 g a.i. ha^-1), CP + metribuzin (59.3 + 39.53 g a.i. ha^-1) in comparison with 2-hand weedings (35 and 45 DAS) and control [weedy check].

Results: The results showed that wheat variety HD 2967 and pre-emergence application of pendimethalin + pyroxasulfone (1000 + 125 g a.i. ha^-1) recorded significantly highest crop dry matter, test weight and grain yield, simultaneously recorded the lowest density, biomass of broad-leafed weeds, highest weed control efficiency and weed control index.

Interpretation: Wheat variety ‘HD 2967’ and pre-emergence application of pendimethalin + pyroxasulfone (1000+125 g a.i.ha^-1) was effective in the management of weeds and, recorded highest growth parameters and yield.

Key words: Herbicide mixtures, Weed control efficiency, Wheat cultivars
