Harvesting grain per hectare of crop rotation area 3.88 t / ha, fodder. units - 9.0 t / ha, protein - 0.66 t / ha. (var.2). In crop rotation (option № 9), with the introduction of N560 P580 K580, productivity in feed yield. from increased by 165%, and the output of the river. - 145% compared to the option without mineral fertilizers. Coefficients of variation of productivity indicators of 7-10-field crop rotations vary in the range of 12.1-14.8%, which indicates the stability of crop rotation productivity over time. In five-crop rotations with grain saturation, 60-80%, including 20% ​​corn, had a higher forage harvest. from - 8.33 - 8.86 t / ha than in crop rotations with early grain - 5.20 - 5.95 t / ha, and the highest in crop rotation with two fields of corn (var.10) - 9.81 t / ha , digestible protein 0.73 t / ha at the cost of feed. from 1438 UAH / t, grain 2569 UAH / t / ha profit 37154 and profitability 263.3%. The greatest economic efficiency of ten-field crop rotations was obtained in crop rotation with soy saturation of 20%, grain 80%, including wheat -30%, corn for grain 30%: fodder. from 8.19 t / ha, protein 0.8 t / ha, net profit 35992 UAH / ha with a profitability of 221.6%, costs are 16243 UAH / ha. Seven-field crop rotation of var.13 with grain saturation - 72%, 43% of them corn, 14% - wheat and barley + 14% sunflower + 14% - grasses - 9.6 t / ha of fodder had higher efficiency. units, 0.55 t / ha of protein with a net profit of 30553 UAH / ha at a profitability of 190.8%, costs were 16012 UAH / ha, the cost of feed unit - 1668 UAH / t, grain - 1213 UAH / t. The most effective three-field crop rotation soybeans - corn - corn, feed yield. from 9.49 t / ha, Product Description popup.authors popup.nrat_date 2022-03-09 Close
