The article evaluates and outlines the main aspects and vision of optimization of sunflower fertilizer through the use of modern biological products of complex bioorganic and biomineral nature through their use in the form of foliar fertilization. The relevance and importance of such technological solutions and the search for optimal options for maximizing the yield potential of modern sunflower hybrids are emphasized given the importance of this crop for the formation of agricultural potential of Ukraine. The peculiarities of sunflower mineral nutrition for a long cycle of its study are generalized and aspects of its nutrition optimization and expediency of application of complex and growth-regulating biologicals are determined. The hydrothermal conditions of sunflower vegetation for the two-year cycle of application of biological products for vegetation were evaluated, which allowed to evaluate the role of their components on the growth processes and crop formation of sunflowers. The effectiveness of different variants of BTU-Center biological preparations recommended for growing sunflower for foliar feeding - Organic Balance and BTU Biocomplex was studied in view of the regulations of their use in terms of critical phases of growth and development of culture with a dose interval of 0.5 l / ha (single application) up to 1.0 l / ha (double application) in phases 6-8 and 12-14 leaves in combination with application of bioadhesive Liposam (0.5 l / ha) and urea (7 kg / ha) to enhance the physiological action of biological products. The efficiency and expediency of using both studied drugs with technological significant advantage in the use of high-yielding sunflower hybrids on gray forest soils in the Forest-Steppe zone of the right-bank biological product Organic Balance in the variant of double use. %, an increase in the area of the assimilation surface by 19.6%. As a result, it was found that the highest yield of sunflower hybrid LG 5638 on average during the study period was formed in the variant of double use of biological product Organic Balance - 2.84 t / ha with an increase to control of 0.39 t / ha (15.9%).
