Productivity of five-field crop rotations in the zone of sufficient moisture of the Right-Bank Forest Steppe

Goal. To assess the direction of nature changes in productivity 5-field crop rotations and to determine their energy efficiency on podzolized chornozem Right-Bank Forest Steppe under influence rotation factor fertilizer systems. Methods. Field, laboratory, quantitative, comparative calculation, mathematical statistical. Results. It was established that total depended share grain, technical fodder crops, applied The output grain units from 1 ha area for 80–100% saturation with crops 5.95–9.10 t, 40–60% — 5.89–9.01 6.06–8.40 coefficient 3.31–8.39 standard units. largest harvest (9.43 tons) provided by 20% perennial leguminous grasses, 60% cereals, sugar beets organo-mineral system. 6.63 Conclusions. In conditions sufficient moisture Forest-Steppe chernozems, during development structure sown areas rotation, it is necessary take into account ratio between different groups which will ensure an increase agriculture. During current crisis, advisable correct saturating production «energy-cheap» crops.
