Abstract
In the extreme climate and takyr-like low-humus soils of the Surkhandarya
region, located in the southernmost desert zone of Uzbekistan, the study of the influence of winter wheat and repeatedly sown oilseeds on soil fertility, wilt of fine-fiber cotton, and cotton yield under short-rotation crop rotation is the most pressing problemof agriculture.As a result of the accumulation of organic substances in winter wheat and various oilseeds sown after it and their mineralization, an increase in soil humus and other nutrients, soil fertility, improvement of the agrophysical and agrochemical state of the soil, and a decrease in the damage caused by wilt, as a result of which the cotton yield of fine-fiber cotton increased by 4.5-5.5t/ha-1compared to the control, and the level of profitability of the farm increased by 20-25%.
