Abstract

The interest and spread of eggplant culture are defined worldwide due to the nutritional and dietary properties of the fruits. Nowadays, there is a rising trend towards increasing the areas under eggplant in plastic ground greenhouses. Nevertheless, the issues of the production of high-quality eggplants are essential. The studies were performed from 2018 to 2021 on the territory of the V.I. Edelstein Educational and Scientific Production Center for Horticulture and Vegetable Growing at the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. Two methods of plant formation (two and three stems), rationing of flowers in the inflorescences of eggplant plants (without rationing, rationing for a flower, rationing for 2 flowers), and eggplant hybrids were studied. As a result of the study, the agrobiological features of growing eggplant plants in plastic ground greenhouses were defined. The highest vendibility of the fruits of the studied hybrids was observed during the formation of plants in three stems, with rationing and preservation of the first flower in the inflorescence - 87.6%, rationing for two flowers – 82.8%, and without rationing of flowers – 77.2%.
