Abstract
The results of studies on the effect of organo-mineral fertilizer on agrobiological and econom-ic indicators of Cabernet Sauvignon grapevine variety are presented. To determine the biologi-cal effectiveness of the fertilizer on grapevine, foliar feeding of Cabernet Sauvignon plants was carried out during the phase of inflo-rescence advancement and 15 days after. Foliar feeding of plants with organo-mineral fertilizer had a positive effect on the formation of berries and clusters, contributing to an increase in their mass. At the drug consumption rate of 5.0 l/ha and 7.0 l/ha, both the number of berries in a bunch and the weight of one berry significantly increased compared to the control. The use of organo-mineral fertilizer also contributed to bet-ter pollination and an increase in berries in bunches, which together contributed to an in-crease in yield, depending on the applied con-sumption rates, by 8.7‒11.6 %. Estimation of quality characteristics of berry juice during har-vesting showed its compliance with standard varietal conditions in all variants of the experi-ment, despite the significant differences in the mass concentration of sugars between the con-trol and variant 3 (7.0 l/ha). The acidity of berry juice differed insignificantly between the vari-ants and the control. When feeding plants with organo-mineral fertilizer, the growth activity of shoots significantly increased in all variants of the experiment compared to the control variant. An increase in the activity of growth processes led to a decrease in shoot maturation (73.2‒74.4 %) at all drug consumption rates compared to the control (84.9 %). However, the percentage of shoot maturation in all variants is high enough for successful overwintering of plants.
