RESULT:

‍

1. Yield increase compared to control with NPK: 6.05-19.43%.
2. Yield increase resulted from improvements in yield structure: the number of productive stems increased by 6.1–18.7%, the length of the spike increased by 3.4–6.9%, the number of grains per spike increased by 2.3–8.9%, and the mass of 1000 grains increased by 2.7–6.2%.
3. Quality indicators of the grain also increased: the protein content in the grain increased by 0.68–1.16% (in absolute values), and the gluten content increased by 1.2–2.1% (in absolute values).
4. The maximum result was achieved with a double application at a 3.0 kg/ha dose.
5. The maximum yield increase exceeded the experimental error and was statistically significant.
