The problem of improving the quality of winter wheat grain is relevant and at the same time relatively difficult to solve. In many farms of the republic, in recent years, the yield of winter wheat grain on irrigated lands is 50 c / ha and more. However, the quality of the grain remains low, the protein content in the grain ranges from 10-12%, and the amount of crude gluten in it is in the range of 19-25%. This protein content in winter wheat grain is significantly below the established standard. Foliar dressing has a positive effect on the physiological processes in winter wheat. With foliar feeding, metabolism, photosynthesis and transpiration process are significantly improved, the growth and development of plants is accelerated. In the experiment, with foliar feeding, in the winter wheat variety Kroshka, an increase in the total leaf surface by 6.5-13.8 thousand rubles was observed. m2, biological yield increased by 17-59 c / ha, grain was 59.2-74.7 c / ha. The increase in biological yield varied from 18.1 to 54.9 c / ha, and the increase in grain yieldfrom 6.7 to 22.2 c / ha.
