Based on the obtained data, the effect of foliar fertilization on soil fertility indicators is not observed because the assimilation of fertilizers by plants occurs directly by the aboveground vegetative mass. According to the yield of vegetable crops, there is an increase in indicators with options with foliar fertilization by 4,1-8,8% and marketability by 1-5% in tomatoes and 1,3-4,9% on cucumber plants in accordance with the background of the main application of fertilizers and marketability by 1-4%, where the highest growth rates were recorded in the areas of the main organo-mineral fertilizers. Also, the interruption of permanent cultivation by the crop rotation link allows to obtain a yield higher by 8-9,5%. The highest level of relatively net tomato yield (177,5 thousand UAH / ha) and profitability (165,4%) is observed for permanent cultivation with organo-mineral fertilizers and fertilization. And on cucumber crops according to the recommended technological methods (interruption of permanent cultivation by crop rotation, basic application of organo-mineral fertilizers and fertilization) conditionally net profit per unit area – 172,2 thousand UAH / ha and the level of profitability -140,4%.
