Abstract In Ukraine, the development of horticulture has been growing rapidly over the last decade. It is explained by favorable soil and climatic conditions for the industry, introduction of intensive cultivation technologies and considerable demand for horticultural products. The productivity of fruit plantations depends on a number of factors: the design of the plantations, agro-ecological conditions of cultivation and agro-technological methods of care for them, especially the fertilizer system. Together with soil fertilizer in gardening, the foliar feeding method is widely used; it is used when, due to adverse weather conditions and a weakened soil condition, the efficiency of nutrient absorption by the root system of fruit crops reduces. The results of the study of formation of growth indices of pear trees and yield of fruits of Zolotovorotka variety grown on dark grey podzolic soil in the Right Bank Forest Steppe, depending on the application of foliar feeding with nitrogen together with microelements on an optimized background of soil nutrition of the main macroelements are considered. As a result of researches it has been established that application of foliar nitrogen fertilization together with micro fertilization REACOM SR-CO on the background of optimized soil fertilization and without fertilization had positive influence on phytometric indexes of productivity of trees in comparison with control variants and provided optimal for intensive gardens average growth of shoots. The application of optimized soil fertilizer also contributed to the increase of yield by 16,2 %, and foliar fertilization with nitrogen together with macro elements on optimized soil nutrition background — by 25,7 %. The complex fertilizer increased the average weight of the fruit, and the yield of the highest and first commercial grade fruit did not change significantly.
