The recommended cultivar for top quality wines Riesling in the vineyard of Grocka (Serbia and Montenegro) is in full crop. It was grafted on Kober 5 BB stock and planted on the soil type cambisol. Microbiological fertilizer was used in the study - biological preparation prepared with mixed natural populations Azotobacter chroococcum, Bacillus megaterium and Bacillus circulans. The space in row is idle land and the space between rows was sown each year (March-April) with a mixture of field pea and barley and ploughed in the inflorescence phase of legumes. Grape yield varied between 8772-6804 kg/ha. Microbiological fertilizer with Azotobacter had the highest yield and the control treatment had the lowest yield, where only grass mixture was sown. Extremely dry conditions in the trial period caused the grape yield in cv. Riesling to be extremely low. In combination of fertilizers Bacillus megaterium + Bacillus circulans wine with the most ethanol, extracts and polyphenols was obtained. The wine obtained from the control treatment had a typical taste.
