Abstract
The article presents the results of studies of 2018–2019, conducted in the soil and climatic conditions of the South-Western zone of viticulture of Crimea, on the assessment of the influence of domestic micro-fertilizers on the growth, economic and uvological indicators of table grape variety ‘Muscat Yantarnyi’. It was experimentally proven that the use of the studied mineral nutrition systems with Organomix and Forris microfertilizers for foliar treatments of the vine allowed to increase significantly the yield by an average of 9.4% (1.7 t / ha), the weight of the bunch - by 9.5% (13.1 g), the volume of bush growth - by 8.3% (261.9 cm3), to reduce the millerandage of the bunch by 8.6% in comparison with the control.
