Productivity of buckwheat in 6-field crop rotations in the conditions of the Left Bank Forest Steppe

Abstract

Aim. The purpose of the study is carried out in the established structure of influence, recruitment and placement of field crops in various crop rotations on overall productivity, yield and quality of buckwheat in particular. The study was carried out in the subzone of unstable moistening of Left Bank Forest-Steppe of Ukraine on typical low-humus Panfilska chernozem research station of the NSC «IZ NAAN». Methods. Growing technology of agricultural crops in experiments is generally accepted and recommended for the research area. Chemical means of protection were used plants for the production of competitive marketable buckwheat products. Results. Studies conducted in a long-term inpatient setting field research, which was established in 2001, on the study of crop rotations on typical ones chernozems of unstable moistening of the Left Bank Forest Steppe, convincingly testify to the fact that during 2016–2020 the research is the most 6-field crop rotations are rational in this zone: soybeans – winter wheat. – sugar beets – spring barley – corn for grains – buckwheat; buckwheat – winter wheat – soybean – spring wheat – winter rye – spring barley for organic of the mineral intensification system (by-products of the precursor + N40P40K40 for buckwheat). Conclusions. Buckwheat yield, which was grown after corn for grain and spring barley as precursors and corresponding set crop rotation, was in the range of: 2.05–2.10 t/ha, while the content of raw protein was contained at the level of 14.7–15.0%. Economic efficiency growing buckwheat in the structure of 6-field crop rotation becomes: conditionally net income – 13.89–14.48 thousand hryvnias/ha for a high level profitability – 130–135%.
