2. Background NPK + Seed Treatment. Foliar application: 1st - in the rosette phase and then 2 times with an interval of 14 days, product consumption - 0.5 kg/ha, working solution consumption - 300 l/ha.
3. Background NPK + Seed Treatment. Foliar application: 1st - in the rosette phase and then 2 times with an interval of 14 days, product consumption - 1.5 kg/ha, working solution consumption - 300 l/ha.
4. Background NPK + Seed Treatment. Foliar application: 1st - in the rosette phase and then 2 times with an interval of 14 days, product consumption - 3.0 kg/ha, working solution consumption - 300 l/ha.

RESULT:

1. Yield increase compared to control with NPK background: 3.28-15.89%.
2. The increase in yield resulted from improvements in the yield structure.
3. Cabbage head mass increased by 3.7-4.8%, cabbage head diameter by 2.7-8.1%, and cabbage head height by 1.4-7.5%.
4. The content of dry matter increased by 0.5-0.9% (absolute values), vitamin C by 2.8-6.0%, and the sum of sugars increased by 6.1-12.1%.
5. The maximum result was achieved with a triple application at a dose of 3 kg/ha.
6. All yield increases exceeded the experimental error and were statistically significant.
