APPLICATION:

‍

1. Control. NPK background.
2. Background NPK + Fe20. Foliar application: 1st - in the tillering phase, 2nd - in the boll phase, product consumption - 1.5 kg/ha, working solution consumption - 300 l/ha.
3. Background NPK + Fe20. Foliar application: 1st - in the tillering phase, 2nd - in the boll phase, product consumption - 2.0 kg/ha, working solution consumption - 300 l/ha.
4. Background NPK + Fe20. Foliar application: 1st - in the tillering phase, 2nd - in the boll phase, product consumption - 3.0 kg/ha, working solution consumption - 300 l/ha.

RESULT:  

1. Yield increase compared to control with NPK background: 3.75-14.38%.
2. The yield increase resulted from improvements in yield structure: the number of productive stems increased by 7.1-16.9%, spike length increased by 5.1-6.8%, the number of grains per spike increased by 2.0-8.6%, and the mass of 1000 grains increased by 1.5-6.7%.
3. Grain quality indicators also increased: protein content in the grain increased by 1.09-1.39% (in absolute values), and gluten content increased by 2.4-2.8%.
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.
