Effect of inorganic fertilizers on the clover growth in gray-brown soils

The presented article presents materials on the effect of mineral fertilizers on the height of clover on irrigated gray-brown soils of the Ganja-Gazakh region. Due to the biological nitrogen collected by clover in the soil, more than twice the annual rate of nitrogen is saved in one cycle, thereby supplying other agricultural fields with nitrogen. Therefore, given the role of cotton as a strategically important plant, and alfalfa as a strong feed for livestock and restoration of soil fertility, the study of the fertilizer system of both plants in the cotton-alfalfa crop rotation is one of the most urgent tasks. The application of mineral fertilizers to alfalfa plants on irrigated gray-brown (chestnut) soils had a significant impact on alfalfa growth. High altitude means high yield. During the years of research, the highest height was observed in the N60P90K60 variant on average over 3 years. Depending on the norms of mineral fertilizers, the height of alfalfa increased by 6.3-29.5 cm compared to the variant without fertilizers.
