Main Article Content
The aim of the scientific article is to develop agricultural technology to ensure high yields of winter wheat grain on irrigated lands in Uzbekistan by using a combination of the depth of the main tillage, the type and norms of herbicides in the fight against weeds in the fields of winter wheat. The article presents the results of soil cultivation 14-16 cm (cheeslanding) and 4-6 cm (harrowing) in the control against winter wheat weeds on typical irrigated and meadow sierozem soils of Uzbekistan. Weed seeds are mainly distributed in the soil layer of 0-10 cm (68.7-100%), when plowing to a depth of 30-35 cm, the soil is cultivated in a layer of 25-35 cm (66.7-63.2%). and in the first year of plowing 30-35 cm, in the second and third years with chisel tillage by 14-16 cm Annual weeds (33 of species) in winter wheat 86.8-95.7% and 47.4-50.8%, perennials (25 of species) 45.4 -42.8%, Application of Atlantis -3.6% herbicide 250 g/ha or herbicides Granstar-75% DF and Puma Super-7.5% at the rate of 15 g/ha + 0.8 l/ha when harvesting winter wheat, annual weeds decreased by 92.3-92.9 and 87.8-94.4%, and perennial by 41.6-33.3%, respectively, 59.7-51.0 and 63.4-67, 2 c./to high winter wheat grain yield.
