Korshevnyuk S.P. Formation of lentil grain productivity depending on pre-sowing treatment of seeds and foliar fertilization in the conditions o of the Right-Bank Forest-Steppe of Ukraine. - Qualification scientific work with manuscript rights. Dissertation for obtaining the scientific degree of Doctor of Philosophy in specialty 201 Agronomy. - Vinnytsia National Agrarian University, Vinnytsia, 2023. The dissertation work is devoted to the study of the processes of growth and development of lentil plants, the formation of the assimilation surface and symbiotic potential, with the search for optimal options for the implementation of the said processes in the size and quality of the formed crop with the pre-sowing treatment of seeds with inoculant and microelements and the implementation of a system of foliar fertilization. The dissertation studied the peculiarities and regularities of the growth of the vegetative mass of plants in relation to the development and formation of their assimilation surface and the species structure of symbiotic potential. The activity of the photosystem of lentil plants was studied based on its response to the application of technological measures to optimize lentil nutrition in view of the basic and indicator indicators of the chlorophyll fluorescence induction curve. The peculiarities of the formation of the individual structure of grain productivity, qualitative indicators of the chemical composition of grain are determined. Based on the application of correlation and regression analysis, optimal hydrothermal regimes of lentil vegetation were formulated, which, in interaction with the applied technological measures to optimize plant nutrition, will ensure the maximum realization of the yield potential of this agricultural crop. The dissertation presents specific ways of solving the scientific problem of stabilizing and increasing the realization of the yield potential of zoned lentil varieties due to a comprehensive approach to improving its nutrition in the system of both pre-sowing seed preparation and due to its technological correction in the option of selecting optimal options for foliar feeding during the growing season.
