Vorobiova N. Scientific bases of formation of productivity of vegetables of a family nightshade and quality of production in the Forest–steppe of Ukraine

Qualifying scientific work is devoted to topical issues of formation of productivity of early potato and tomato plantations in the Forest–Steppe of Ukraine. The spectrum of adaptive ability of early potato cultivars, cultivars and hybrids of tomato is considered, the research on comparison of efficiency of selection of assortment, processing of seeds, seedlings and vegetative plants of potato and tomato by biological products on growth, development and productivity is generalized. The efficiency of application of different forms of absorbent in potato plantations is studied. New approaches to the use of vermicompost for growing tomato seedlings have been developed, the technology of obtaining early yields of early potatoes by improving the use of temporary shelter from agrotextile of different density in the Forest–Steppe of Ukraine and theoretically substantiated biologized cultivation technology. The analyzed the scientific works of domestic and foreign scientists on the study of biological features and their impact on the production processes of early potatoes and tomatoes. A systematic analysis of the results of research on the influence of biologically active substances, biological products and vermicompost on the formation of productivity indicators of early potatoes and tomatoes. The research was carried out during 2013–2020 in the conditions of the training and production department of Uman National University of Horticulture. The research program provided for the study of the adaptive ability of potato varieties, varieties and hybrids of tomato and to determine the impact of assortment on the efficiency of cultivation technology; detection of the effect of biologically active substances and biological products on the productivity of early potatoes and tomatoes; the influence of temporary shelter of early potato plantations on obtaining an early harvest and studying the effectiveness of vermicompost as a substrate for growing tomato seedlings in the Forest–Steppe of Ukraine.
