“…The grape plant has a high plasticity in the conditions of the display of natural biotic and abiotic stressors. This biological character allows the plant to grow and bear fruit effectively in conditions of a lack of mineral nutrition and precipitation, to tolerate high maximum and low minimum air temperatures [1][2][3][4][5][6]. At the same time, grape plants respond positively to optimal environmental conditions [7][8][9][10][11].…”

The grape plant reacts by modification variability of phenotypic traits to the variation of weather conditions. The reaction of the Augustine and Moldova grape varieties to the variability of natural conditions was ambiguous. In the Augustine, the lower limit of the modification variability of the cluster mass is 354 and the upper limit is 410 g, the grape yield is 8.1 and 11.5 kg/bush, the sugar content of the berry juice is 15.8 and 17.5 g/100 cm3, in the Moldova, respectively, 387 and 457 g, 9.6 and 13.2 kg/bush, 16.4 and 17.8 g/100 cm3. The reaction norm of the Augustine according to the phenotypic traits is following: the cluster mass is 56 g, the yield is 3.4 kg/bush and the sugar content is 1.7 g/100 cm3, of the Moldova, respectively, 70, 3.6 and 1.4. Against the background of the application of fertilizers, the lower and upper limits of variability have increased as well as the reaction norm by cluster mass and yield, however reaction norm by sugar content decreased.

The article presents the results of studies of 2019-2020, carried out in the soil and climatic conditions of Crimean Mountain-valley viticultural zone on table grape variety ‘Italia’. It was experimentally determined that five-fold foliar treatment of grape plantations with gel fertilizers has led to a significant increase in the average length of annual shoots by 15 cm (9.2%) and an increase in the green matter of bushes by 165.1 cm3 (9.1%). It was found that using of preparations of experimental system of mineral nutrition manufactured by Agrinos and Lima-Europe companies during two growing seasons of grape plants has led to an increase in the average bunch weight by 42.9 g (7.4%), shoot productivity by 8.1% and an increase in the cropping capacity by 1.8 t/ha (10.2%) in comparison with the control. Using of the studied mineral gel fertilizers against the background of increasing grape productivity did not affect the process of sugar accumulation and the level of titratable acids. The studies showed that two-year fertilizer utilization of the studied system of mineral nutrition contributed to a significant increase in organoleptic characteristics of table grapes.
