Effect of herbicides and irrigation methods on growth and yield traits of Bread wheat Crop (Triticum aestivum L.) and its companion weeds

Abstract

This experiment was conducted to study the effect of weed control herbicides accompanying the soft wheat crop under rainy and irrigated conditions in wheat fields  for the 2022-2023 agricultural season and to study the extent of the impact of these factors on the characteristics of the crop, its components, and the weeds accompanying the crop. The experiment included three factors: The first factor was two irrigations systems, the second factor was two varieties of bread wheat and the third factor was three types of selective herbicides to weeds control in wheat fields  according to RCBD design with a factorial experiment system with three replications. The results indicated there was effect of herbicides and irrigations systems on all the traits of the varieties had effect as the Babel variety outperformed the Baghdad variety in (plant height, leaf area, Number of spikes, weight of 1000 grains, and grain yield. As for the irrigations system, it was superior to the demotic system in terms of (plant height, leaf area, number of spikes, weight of 1000 grains, and grain yield). As for herbicides, The herbicide Tarzek was superior to the herbicide Axial and the comparison treatment in terms of G.y, weight of 1000 grains, number of branches, and leaf area, did not differ significantly with Prince herbicide. As for the weed traits, Prince herbicide was superior to Tarzek and Axial herbicides have effect on all characteristics, except for the weight of 1000 grains, which was significant.
