Abstract
Information is provided on the positive effect of complex fertilizer (NPK) with microelements in chelated form on the productivity of grape-vine plantings of Cabernet Sauvignon variety. Foliar feeding was carried out 2 times during the growing season − in the phase of inflorescence formation and in the phase of berry growth. Feeding plants with an agrochemical in doses of 4.0 and 6.0 l/ha contributed most to the increase in the number of berries in a bunch and their weight, which led to an increase in yield by 24.0...28.4 % compared to the control. With a significant increase in yield in the 6 l/ha option, a decrease in the content of soluble sugars in the berries and an increase in titratable acids were observed compared to the control. Despite the fact that the berry juice conditions in the variant with a dose of 6.0 l/ha did not go beyond the standard for the Cabernet Sauvignon variety, the recommended dose of fertilizer was − 4.0 l/ha.
