Abstract: The results of studies on the effect of fertilizer with a complex of macro- and microelements on the economically valuable indicators of Kunlean grapevine variety are presented. For this purpose, foliar feeding of Kunlean variety vine was carried out in the phases of the beginning of flowering and in the end of flowering. With foliar feeding with fertilizer in doses of 3.0; 4.0; 5.0 l/ha, there was an increase in the weight of berries and clusters, as well as the number of berries in a bunch, which contri-buted to an increase in yield, depending on the dose of fertilizer, by 21.2−22.6% compared to the control. Fertilizer feeding had a positive ef-fect on the quality of the crop. The mass concentration of sugars significantly increased in all experimental variants (3.0; 4.0; 5.0 l/g) by 3−5% compared to the control. The significance of the differences was proven for the control and other options, as well as for options with a fertilizing dose of 3.0 and 5.0 l/ha. The mass concentration of titratable acids was lower in the variants with all doses of fertilizer, compared to the control by 1−4%, depending on the experimental variant. It is recommended to use a fertilizer dose of 4.0 l/ha, since increasing the dose to 5.0 l/ha does not lead to a significant improvement in the studied grapevine productivity indicators
