To obtain high efficiency of grain farming, a scientifically based farming system is needed, taking into account advanced technologies for the use of fertilizers that correspond to the specific natural and economic conditions of the region, district, individual farm and field. The purpose of this study is to study the effect of mineral fertilizers on the agrochemical properties of the soil, yield and quality of corn grain grown under monoculture conditions. Field experiments were conducted in 2021-2022. in the conditions of the foothill zone of the CBD on a hybrid of corn "Krasnodar 193 MV", guided by the methods adopted in agriculture. Due to its biological characteristics, corn tolerates permanent crops well and has a high responsiveness to mineral fertilizers. On the site selected for research, corn is grown continuously for 8 years. In our experience, the highest yield of 79.2 c/ha was given by option 4 with a dose of fertilizers - N60P60K60, while the increase was 15.8 c/ha or 24.9%. We can assume that the intensive nutrient cycle occurring at the expense of the microbial community under corn directly affects the productivity of cucumbers.

With increasing doses of fertilizers, there was a gradual increase in protein content from 8.69% in the control to 11.06%. As for starch, its highest content was at the control – 65.7%.

In the variants with fertilizers, the starch content decreased by 1.3-2.8% and its lowest content was in the 4th variant with a dose of fertilizers N120P90K45. The increase in the fat content in corn grains from the action of mineral fertilizers was insignificant and this can only be considered as a trend.

Thus, the cultivation of corn in a monoculture in agroecological conditions of the foothill zone of the CBD is possible without a significant decrease in productivity and grain quality, provided that N60P60K60 is applied.
