RESULT:

‍

1. Yield increase compared to control with NPK background: 7.1-15.24%.
2. The yield increase resulted from improvements in yield structure: the average fruit mass increased by 8.9-16.3%, and the length of the fruit increased by 6.7-16.0%.
3. Among the quality indicators, the treatment only influenced vitamin C content, which increased by 29.8-42.1%.
4. The content of nitrate and sugar mass fraction remained unchanged.
5. The maximum result was achieved with a triple application at a 3.0 kg/ha dose.
6. All yield increases exceeded the experimental error and were statistically significant.
