Subject of research: varieties of barley, peas, mineral fertilizers, elements of crop structure, level of grain yield. The purpose of the research is to develop a scientific concept of the formation of biocenoses of spring grain and legume crops with high adaptability to changing conditions of the Steppe. Research methods: field, laboratory-field experiments, methods of hypotheses, synthesis, analysis, measurement and weighing, mathematical statistics and economic. A scientific concept of the formation of biocenoses of spring grain and legume crops with high adaptability to changing conditions of the Steppe has been developed. On average over 5 years (2021−2025), the best in terms of productivity among spring barley varieties selected by the Breeding and Genetics Institute were Aeneas (4.32 t/ha), Avatar (3.83 t/ha), Adapt (3.67 t/ha), Stalker (3.64 t/ha), Mouravi (3.68 t/ha); selected by the V. Ya. Yuryev Institute of Plant Breeding - the Avgur variety (3.58 t/ha); selected by the State Institute of Grain Crops - the Ilot variety with a yield level of 4.01 t/ha. High results in terms of grain yield were also provided by spring barley varieties selected by the Steppe Institute of Agriculture - Sozonivskyi (4.31 t/ha), Statok (4.38 t/ha), Doridnyi (3.76 t/ha).
