The purpose of research - To develop ecologically balanced crop rotations with different structures, ratios and locations using scientifically sound doses of mineral and organic fertilizers (by-products of each crop), chemical plant protection products in the climate change of the Forest-Steppe of Ukraine. Research methods - long-term field, laboratory-field, vegetation experiments, laboratory research (chemical, physico-chemical, microbiological). Soil - chernozem typical shallow low-humus coarse-grained light loam. On chernozems of typical low-humus in the subzone of unstable moisture of the Left Bank Forest-Steppe multi-rotation (4-8-field) crop rotations with grain saturation from 57.2 to 100% and application of intensification means provided: four-field grain crop rotations: peas-winter wheat-corn-corn for mineral, organo-mineral and organic fertilizer systems - harvest from 1 ha of arable land: grain - 5.03-5.93 tons, fodder units - 8.79-10.30, grain units - 6.40-7.50 and digestible protein - 0.70-0.83 tons. High yields of cereals 6.71 t / ha provided five-field crop rotation: peas-winter wheat-sunflower-spring barley-corn for grain, harvest from 1 ha of arable land: grain is 5.37, feed units - 10.41, grain units - 8.70 and digestible protein - 0.89 tons. Among the studied models of rotational crop rotations, the highest profit was provided by 5-field crop rotation: winter peas – winter wheat – sunflower – spring barley – corn for grain by organo-mineral fertilizer system, where the profit was 19.20 thousand UAH / ha at a profitability level of 137% and eight-field crop rotation is 62.5% saturated with cereals, 25 fodder and 12.5% ​​industrial crops.
