The work presents the study results of the effect of microbiological fertilizer EcoRic (Bacillus subtilis subsp. Subtilis, strain BR-1256 - 1-10x9CFU / cm3 ) on the wine grape variety of �Bastardo Magarachskiy� in the conditions of the South Coast of Crimea. The objectives of the research included determining the effect of the studied fertilizer on the quantitative and qualitative indicators of grapes. Crop formation and ripening took place under the hot and dry summer conditions. It was found that double foliar treatment with microbiological EcoRic fertilizer in the application rate of 2.0, 3.0 and 4.0 l / ha during the period of active growth of shoots (the inflorescence emerge (according to the BBCH-scale53)) and at the beginning of grape flowering (�the inflorescences fully developed, flowers separating"(according to the BBCH-scale57) � "first flower hoods are detached from the receptacle"(according to the BBCHscale 60) had a proper positive effect on increasing in the cropping capacity of grapes per 1 ha: with the rate of application of 2.0 l / ha � by 0.93 t / ha (9.1 %); 3.0 l / ha � by 1.62 t / ha (15.9 %); 4.0 l / ha � by 2.43 t / ha (23.8 %). Double foliar application of the studied fertilizer also contributed to an increase in the average bunch weight by 10.0-24.3 %, an increase in the yield per one record bush by 0.42-1.01 kg (9.1-22.0 %), the leaf surface area of the bush (m2 ) � by 16.3-37.2 %, the average shoot length � by 16.8-22.3 %. The yield collected from variants with foliar application of microbiological EcoRic fertilizer, in terms of quality indicators, was higher than that collected from the control: in that number by mass concentration of sugars in a berry juice � by 10.0-22.3 (4.7-10.5 %) g / dm3.
