Abstract
The article describes the role of the non-traditional leguminous crop Crotalaria (Crotalaria juncea L.) grown in the conditions of the degraded meadow-alluvial soil of the northern region of the republic, Khorezm region in increasing soil fertility, as well as the effect of planting time and standards on the amount of nutrients in the soil as influence of elements of cultivation technology. In the experiment, mobile phosphorus and exchangeable potassium substances in the soil decrease towards the end of the application period, and the amount of nitrate nitrogen increases to 0.81-1.9 mg/kg as the planting rate increases from 10 kg\ha to 18 kg\ha compared to the initial state. The amount of humus also increased by 0.013-0.015% in 3 years, and its positive effect on the improvement of soil fertility was scientifically proven.
