"Theoretically substantiate highly productive crop rotations in relation to climate change with different specialization of agricultural production in the conditions of the Left Bank Forest-Steppe of Ukraine" popup.stage_title Head Shapoval Ivan S., Кандидат сільськогосподарських наук Registration Date 06-01-2024 Organization Cherkasy State The Agricultural Experimental Station of National Scientific Center "Institute of Agriculture of National Academy of Agrarian Sciences of Ukraine" popup.description2 The influence of the ratio of crops in crop rotations with a long rotation on the productivity of multi-rotational crop rotations was studied. The structure of sown areas has been improved: the optimal 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%, sunflower up to 20%, oil radish and soybeans up to 20% increases (Kee) up to 5.28−5.47. For farms with developed animal husbandry for the production of fodder grain, milk and calves, 5- and 10-day crop rotations with grain saturation of 70–80%, including corn 20–30%, barley and perennial grasses 10–20% provide collection of fodder grain 4.25–4.64 t/ha, fodder units 9.90–11.80 t/ha, digestible protein 0.68–0.83 t/ha. Net profit 14967-18194 hryvnias/ha with profitability 62-79% (var. 13.10). In five-field crop rotations with grain saturation of 60-80%, including 20% ​​corn, there was a higher harvest of fodder units - 9.17-11.2 t/ha, than in crop rotations with early grains - 7.43-8.58 t/ha, and the highest in crop rotation with two fields of corn (var. 10, 16a) 11.2–12.2 t/ha, digestible protein 0.83–0.85 t/ha, based on the cost of feed unit 1988−2012 UAH/t, grain 3591−3928 UAH/t/ha profit 18194−18403 UAH/ha and profitability 79−74%. The most effective three-field crop rotation soybean - corn - corn, output of fodder units 12.2 t/ha, protein - 0.85 t/ha, profit 18403 UAH/ha with profitability 74%, cost of feed unit. 2012 hryvnias/ton, cost price of grain – 3928 hryvnias/ton. A 3-field crop rotation for the production of fodder grain was recommended for farms: var. 16a - soybean - corn - corn, which ensured the collection of 9.27 t/ha of grain units, 12.20 t/ha of fodder units, and 0.85 t of digestible protein /ha, net profit - UAH 9,287/ha and profitability 46%. When growing cereals after peas, corn for silage, surface cultivation is recommended, which provides an increase in productivity by 0.2-0.3 t/ha and fuel savings of 26-35%.
