The article presents the results of observations on the germination of seeds of the studied annual crops of spring barley and field peas when sowing in mixed crops depending on the ratio of components. It is known that the main task of modern agriculture in Ukraine is to increase the yield of grain crops, which will contribute to the formation of plant resources, providing livestock with high-quality complete feed, and the population with food. Spring barley and field peas are among the most common agricultural plants. The aim of the work was to determine the features of the influence of sowing rates on the formation of a productive agrophytocenosis of spring barley and field peas in the conditions of the Right-Bank Forest-Steppe. Field, laboratory, laboratory-field and statistical methods were used during the study. In particular, the article analyzed different sowing rates and their impact on obtaining uniform and friendly seedlings and other indicators. Optimization of seeding rate is an important aspect of agronomy, which allows to increase the yield and improve the quality of spring barley and field pea grain in the conditions of the Right Bank Forest-Steppe. It was established that the optimal number of spring barley seeds is 4.5 million per hectare, while that of field pea was 0.72 million/hectare. It is such seeding rates that contribute to obtaining optimal seedling density and germination. The results of this study can contribute to the optimization of the agricultural industry and increase the efficiency of growing spring barley and field pea in a specific region, taking into account the climatic features of the Right Bank Forest-Steppe. The data obtained can be used in planning crop rotations and forming adaptive technologies for growing mixed crops. This is especially relevant in conditions of climate change and the need to preserve soil fertility. Practical application of the results will allow agricultural producers to use resources more rationally and increase the economic efficiency of management. In addition, the results may be useful for educational purposes in the training of future specialists in the agricultural sector. Further research in this area will allow improving the technologies for growing mixed crops with the involvement of other leguminous crops.
