Sokyrko D. The features of leguminous crops productivity formation depending on the growing technologies in the conditions of the Left-Bank Forest-Steppe of Ukrainе.

Object - processes of growth, development and formation of productivity of peas, grass pea and chickpeas depending on seeding rate and doses of fertilizers, seeds treatment by nitrogen-fixing bacteria and features of their complex interaction in the conditions of the Left-Bank Forest-Steppe. The purpose - to establish and compare features of growth and development, formation of productivity and quality of grain of different legumes depending on elements of growing technology. In the dissertation work, the dependence of the grain yield of peas, grass pea, chickpea on the complex interaction of the studied factors (seed treatment, fertilizer application rates, seeding rates) in the growing technology was established, the comparative assessment of the growing efficiency of leguminous crops for various changing elements of technology was carried out, the best options for their cultivation was identified, the economic and energy expediency of implementation in production was justified. The technology of growing peas, grass pea and chickpeas in the conditions of the Left-Bank Forest-Steppe has been improved. Scientific developments were introduced during 2017-2020 on farms of Poltava region on a total area of 100 hectares. The field of use is agricultural production.
