Currently, in practical agriculture, the role of resource-saving technologies for direct sowing of field crops in-creases; they produce positive results under the correct system of weed control only. To solve this problem, the research in various regions is required. Taking this into account, in the central zone of the Krasnodar Region from 2013 through 2018, we studied the effect of plowing (22-24 cm), surface tillage (6-8 cm) and zero tillage (direct seeding) on weeds after harvesting in the crops of crown flax, winter wheat, foxtail millet in stubble, and field pea. It was found that decreased tillage depth increased the ger-mination of annual weeds in the summer and autumn 1.7-2.9 times higher than after plowing (117 pcs per m2); and before herbicide application on growing crops 1.5-1.9 times higher than in the control (183 pcs m2). The applica-tion of the recommended preparations reduced the weed infestation by harvesting to 5.0-28.0 pcs m2. The applica-tion of fertilizers and chemicals ensured the effectiveness of the trial crops. Under zero tillage, the contingent net income of a crop rotation link made 58.6 thousand rubles ha; the crop yields were as following: crown flax -1.70 t ha, winter wheat -6.05 t ha, foxtail millet in stubble-0.50 t ha, field pea -3.62 t ha, although the yields turned out to be lower by 8%, 7%, 0%, 4%, respectively, than after plowing.
