RESULT:  

1. Yield increase compared to control with NPK background: 16.95-77.97%.
2. The yield increase resulted from improvements in yield structure: cluster mass increased by 1.4-35.7 g, plant productivity by 0.3-2.2 kg, berry mass increased by 8.3-66.7%, and the number of clusters by 18.1-63.6%.
3. Changes in quality indicators did not show a clear trend among the variants. An increase in ascorbic acid content by 5.4-7.9% was noted.
4. The maximum result was achieved with a double application at a 2.0 kg/ha dose.
5. All yield increases exceeded the experimental error and were statistically significant.
