Abstract
The purpose of the research is to establish the influence of the structure, content and placement of field crops in 6-7-field crop rotations on their overall productivity, yield and quality of winter wheat in particular. Methods. The technology of growing agricultural crops in the experiment is generally accepted and recommended for the research area. Chemical plant protection agents were used to grow competitive commercial products of winter wheat. Results. The results of research conducted in a long-term stationary field experiment, which was established in 2001, on the study of crop rotations on typical chernozems of unstable moisture in the Left Bank Forest-Steppe during 2016–2021 for six-field and 2016–2022 for seven-field crop rotations, convincingly indicate that the most rational in this subzone was a 6-field crop rotation saturated with winter wheat by 16.7% (soy – winter wheat – sugar beets – spring barley – corn for grain – buckwheat) under the organo-mineral intensification system (predecessor by-products + N60P60K60). Conclusions. The grain yield of winter wheat, which was grown after soybean, buckwheat and winter rapeseed as predecessors under the appropriate set of crop rotations, was in the range of: 5.62–6.02 t/ha, while the protein content in the grain was at the level of – 12.66–13.67%. The economic efficiency of growing winter wheat in the structure of 6-7-field crop rotations was: conditionally net profit – 14.95–16.99 thousand hrn/ha at the level of profitability – 108–125%.
