The structure of sown areas has been improved: the optimal value of the area of ​​winter wheat in crop rotation is 30%, sunflower - up to 10-20%. Saturation of crop rotation with corn for grain up to 40%, up to 20% with sunflower, 20% with radish oil and soy increases (Kee) to 5.28-5.47. For multisectoral farms producing food and fodder grain with developed livestock, 10-crop rotations with grain saturation of 70-80% have been improved, with one field of perennial grasses: grasses - winter wheat - sugar beets - corn for grain - peas - winter wheat corn for silage - winter wheat - barley + grass. With the collection of grain per hectare of crop rotation area of ​​3.07 t / ha, fodder. from - 9.11 t / ha and protein 0.68 t / ha. Five-field crop rotations with 60-80% grain saturation, namely: peas - winter wheat - soybeans - corn - spring wheat. Harvest from 1 ha of grain 2.95 t / ha, feed un. - 7.84 t / ha, digestible protein 0.62 t / ha. Profit 39628 UAH / ha with a profitability of 240.4%. For farms with developed livestock for the production of feed grain, milk and heifers improved 5- and 10 -type crop rotations with grain saturation 70 - 80%, including corn 20 -30%, barley and perennial grasses 10 - 20% provide collection of fodder grain 3,11 t / ha, fodder. un., 8.51 t / ha, digestible protein 0.65 t / ha. Net profit UAH 28,905 / ha with a profitability of 175%. The most productive crop rotation with grain saturation of 80%, including corn for grain 40%, grain harvest 5.78 - 6.60 t / ha, fodder un. 6.49 - 7.74 t / ha, protein 0.38 - 0 , 45 t / ha, with a net profit of 37677 - 35099 UAH / ha. For farms, 3-field crop rotations for the production of fodder grain were recommended: var.16a - soybean - corn - corn - which provided the collection of grain un. of 4.8 t / ha, fodder. from 9.64 t / ha and digestible protein 0.72.
