Productivity of sugar beet in various crop rotations of the Left Bank Forest-Steppe with organo-mineral fertilizer

Aim. To establish the influence of structure, recruitment and placement field crops in different rotations on general productivity, yield quality sugar beets particular. The research was carried out subzone unstable moisture Left Bank Forest-Steppe Ukraine typical low-humus chernozem Panfil Research Station Institute Agriculture National Academy Sciences. Methods. technology growing agricultural experiment is generally accepted recommended for area. Chemical plant protection agents were used to produce competitive commercial beet products. Results. results a long-term stationary experiment, which established 2001, study crop chernozems Forest Steppe, convincingly indicate that during 2016−2020 period, 8-field rotation turned be most rational this zone saturated with 62.5 % grain, 25 fodder 12.5 technical crops: perennial legumes – winter wheat corn grain agriculture triticale spring barley organic-mineral intensification systems (by-products predecessor + N100 P100 K100 beets). Conclusions. beets, grown after wheat, as precursor corresponding set rotations, range of: 50.86–53.21 t/ha, while harvest at level 13.5–13.7 t/ha. economic efficiency structure multi rotational is: conditionally net profit 70.67–75.05 thousand UAH/ha high profitability 338–362 %.
