Abstract
The results of the study on the efficiency of mineral nutrition system based on the preparation "Algae Super"
("AgroBioCom" LLC Company) as foliar treatment of grapes are presented, evaluation of its effect on the formation of grape
productivity and quality indicators of table grape cultivar ‘Italia’ and wine grape cultivar ‘Rkatsiteli’ is given. Using of experimental system of foliar treatments contributed to an increase in the cropping capacity of grapevine cultivars ‘Italia’ and ‘Rkatsiteli’ by
30.1% relative to the control. An increase in the yield of standard products of the ‘Italia’ cultivar by 4.1% in comparison with the control was registered. When using the "Algae Super" preparation, the mass concentration of sugars has increased by an average of 3.1% (P = 2.59*10-5), against the background of a decrease in the mass concentration of titratable acids - by 6.0-6.5%, relative to the control variants. The overall tasting evaluation of the ‘Italia’ grapevine cultivar aſter treatments was 7.1% higher than the control. The cultivation of grapes when using the preparation “Algae Super” led to a decrease in the final cost of the yield of the cultivars ‘Italia’ - by 22.8%, and ‘Rkatsiteli’ - by 22.1%, against the background of cultivation profitability increase by 125.4 and 58.7%, respectively
