RESULT:  

1. Yield increase compared to control with NPK background: 2.25-17.96%.
2. The yield increase resulted from improvements in yield structure: cabbage head mass increased by 8.3-19.1%, cabbage head diameter increased by 1.4-4.0%, and cabbage head height increased by 5.1-13.7%.
3. The content of dry matter and vitamin C remained essentially unchanged, while the total sugar content increased by 2.9-5.9%.
4. The maximum result was achieved with a triple application at a 3.0 kg/ha dose.
5. All yield increases exceeded the experimental error and were statistically significant.
