Experimental bases of crop productivity depending on agrotechnical conditions

As a result of the research, experimental data were obtained on the yield of cultivated crops depending on the type of crop rotation, fertilizer and treatment systems, and their mutual effect on improving ALSZ on the soils of the Vladimir high plain. The main types of fertilizer systems and their effect on the yield of grasses in crop rotation are described. Experimental data have been used to study the effect of various fertilizer systems on productivity, density, botanical composition, and yield of perennial grasses. It is proved that the yield parameters directly depend on the specific tillage system. The effect of fertilizer doses on the yield and productivity of perennial grasses for 2 years of use was revealed.
