Improving the quality of winter wheat grain is a challenge. By using foliar feeding, the growth and development of winter wheat plants can be accelerated. This method enhances physiological processes like metabolism, photosynthesis, and transpiration. In an experiment with winter wheat variety Kroshka, foliar feeding led to an increase in total leaf surface and biological yield. The grain yield also significantly improved. Overall, foliar feeding can boost the productivity and technological qualities of winter wheat grain.
