The results of research baking properties of wheat spelled, namely, increased protein content, starch and α-amylase activity by improving nitrogen nutrition conditions. Established that most of the figure derived protein use ammonium sulfate and ammonium nitrate in option P60K60+ Ns.a.60 + N60. We found that the protein content in grain spelled, depending on fertilization and year of research, is 19,5–24,5%. The highest protein content was 24.4% in the variant background + Ns.a.60 + N60. Thus,

The high efficiency of the first feeding of ammonium sulfate as gluten content was the highest – 53.7% or higher by 3% compared with ammonium nitrate. In addition to protein and gluten in baking properties affect starch content as a raw material for fermentation. Established that spelled grain has a high starch content. However, improving conditions of nitrogen nutrition reduces the figure of 61.1% in the variant without fertilizers to 57,0–59,0% depending on the variant of the experiment and was not changed by the introduction of phosphate and potash fertilizers (61.0%). Grain spelled grain had higher acidity compared to soft wheat, for which the figure is 3 degrees. Higher acidity caused by higher grain spelled protein as the increased protein content leads to higher content of carboxyl groups.
