The structure of sown areas was improved: the optimal size of the area of ​​winter wheat in the crop rotation is 30%, sunflower - 10-20%. Saturation of the crop rotation with corn up to 40%, with early cereals increases (Kee) from 2.6 to 3.9. For farms with developed livestock farming for the production of forage grain, milk and heifers, 5- and 10-type crop rotations with saturation with cereals of 70-80% were improved, including corn 20−30%, barley and perennial grasses 10−20%, which provide a harvest of forage grain 3.97−4.03 t/ha, feed units 9.23−9.51 t/ha, digestible protein 0.65−0.63 t/ha. Net profit 21812−23173 UAH/ha, with a profitability of 96−104% (var. 13.10). In five-field crop rotations with grain saturation of 60−80%, including corn 20%, there was a higher yield of feed units - 9.51−10.37 t/ha than in crop rotations with early grains - 6.01−6.20 t/ha, and the highest in crop rotations with two fields of corn (var.10.16a) 9.51−10.37 t/ha, digestible protein 0.63−0.66 t/ha, with a cost price of feed unit 2960−2367 UAH/t, grain 5854−4545 UAH/t/ha, profit 23174−24213 UAH/ha and profitability 104−99%. The most effective three-field crop rotation is soybean - corn - corn, the yield of feed units is 10.37 t/ha, protein - 0.66 t/ha, profit is 24213 UAH/ha with a profitability of 99%, the cost of feed unit is 2367 UAH/t, the cost of grain is 4545 UAH/t. For farms, 3-field crop rotations for the production of feed grain were recommended: var.16a - soybean - corn - corn, which ensured the collection of grain units of 7.75 t/ha, feed units of 10.37 t/ha and digestible protein of 0.66 t/ha, net profit is 24213 UAH/ha and profitability of 99%. When growing cereals after peas and corn for silage, surface tillage is recommended, which provides fuel savin Product Description popup.authors Kyrylchatenko Nadiia I. Kravchenko Vitalii P.
