In the scientific article, in the study of the efficiency of agrotechnical and chemical control measures against weeds in the maintenance of onion ( Allium cepa L. ) seedlings in the meadow gray soils of the Samarkand province, when the soil is plowed to a depth of 30-35 cm using a two-layer tube in the fall, 18-22 cm to the soil surface (plowing) soil density decreased by 0.06-0.09 g/cm3 in the tilled 0-30 cm layer compared to the treated options. porosity increased by 1.4%. water permeability was higher by 80.2-82.4 m3. When the soil is plowed to a depth of 30-35 cm, Select 120 KE herbicide is applied at the rates of 0.5-1.0 l/ha in the maintenance of onion seedlings (3-4 ginseng period), one-year weeds are 85.2-93.9 and 84.1 by -96.7%, perennials 67.7-81.4; 69.2-83.9% destroyed. It is stated that the phytosanitary conditions of the cultivated area will be improved, and the yield of commercial onions will be 73.6-74.4 tons/ha and high quality.
