On this basis, to improve and implement ecological and economic rotational crop rotations, which in market conditions will ensure the production of competitive products, reproduction and preservation of soil fertility of the Forest-Steppe of Ukraine. popup.description2 Research objects: the process of changing soil fertility and productivity of 4-8-field crop rotations with different saturation with grain, technical and fodder crops under the influence of the fertilization system. The purpose of the research is to determine the aspects of the influence of agrocenoses, different rotation crop rotations and permanent crops on their productivity, economic and energy efficiency in conditions of unstable moisture. On typical low-humus chernozems in the subzone of unstable moisture of the Left-Bank Forest-Steppe, crop yield depended on the fertilization system, crop share, and placement after the predecessor in the crop rotation.The yield of winter wheat varied from 5.01 to 5.87 t/ha, spring wheat from 3.07 to 4.09 t/ha, spring barley from 2.45 to 4.38 t/ha, peas from 3.35 to 4.21 t/ha, corn for grain from 6.59 to 8.08 t/ha, sunflower from 3.47 to 3.81 t/ha, soybeans from 2.82 to 3.20 t/ha. It was found that the productivity of different rotation crop rotations depended on the set of crops, where the harvest from 1 ha of arable land was at the level of 7.0–10.5 t of feed units and 0.6–1.5 t of digestible protein with the highest indicators in 6-8-field crop rotations with 12.5–16.7% saturation with industrial crops. The harvest from 1 ha of arable land of food grain was the highest in 6-field crop rotation – 3.07 t, digestible protein – in 8-field crop rotation with 25% saturation with feed crops – 1.54 t.Productivity in permanent crops had a direct dependence on the studied crops. Growing winter wheat provided the collection of feed units at the level of 4.9 t and digestible protein - 0.45 t, spring barley - 2.4 and 0.16 t, spring wheat - 3.2 and 0.21 t, respectively. The economic effect of using the crop rotation factor is 12–21%, and the conditional net profit is 900–1100 UAH/ha depending on the length of the rotation with the highest indicators in a 6-field crop rotation at Kee 5.4.
