【 摘 要 】

The experience shows that when constructing soil fertility models, many researchers prefer single-valued regression analysis. This is primarily due to the fact that regression analyses require simpler statistical calculations, and on the other hand, regression equations enable a physical explanation of the process under study. The research goal is to determine the effect of soil fertility indices and mineral fertilizers on the yields of crops (cereals) grown in the Karabakh Steppe on gray-brown irrigated soils.
