Aim. The effect of foliar urea nutrition on grain yield, protein, total protein harvest, and nitrogen content in the grain per spike in winter wheat plants of different varieties was studied. Methods. In the field experiment plants of six different bread winter wheat varieties were fertilized with urea in different ways: 1) control; 2) foliar nutrition with urea at the end of anthesis with a dose of 7 kg N / ha; 3) foliar nutrition with urea in the phase of late milk development. Results. It was found that after nutrition in the first period the yield increased by 7-11%, while after nutrition in the second period it remained practically unchanged in comparison with the control. The applied dose of nitrogen did not have a significant effect on the protein content. Grain productivity increased without reducing protein content in this case, and there was no negative correlation between these indicators. As a result, grain protein content was significantly increased in all varieties. Natalka had the highest indicator, due to the best combination of protein content and yield. The calculations of the increase in nitrogen content in the grain per spike at the end of anthesis showed that it was significantly higher than the out-of-root dose. Conclusions. Thus, it has been shown that foliar nutrition of wheat with urea at the end of anthesis is advisable for increase of protein harvest with the crop. This measure stimulates the functional activity of plants, promotes efficiency of nitrogen utilization. Keywords: nitrogen, grain protein, yield, winter wheat, foliar nutrition.

The United States Department of Agriculture (USDA) grading standards for wheat places hard red spring and hard red winter (Triticum aestivum L. em. Thell) wheat into separate classes. One important criterion for this designation is kernel type. Because of genotypes being released by plant breeders in recent years, distinction between these two classes is difficult for grain graders. As a consequence some people in the grain industry favor placing both of these wheat types into one class. One hazard of this action is that end use properties of these two wheats, according to some industrial firms, is class dependent. We studied quality characteristics of five hard red spring and seven hard red winter wheat cultivars grown at the same three Montana locations in 5 different years to evaluate this concept. Analysis of variance indicated quality differences between classes for all traits except flour yields, which were similar for the two classes. Flour ash content, farinograph absorption, peak time, stability time, valorimeter, grain protein content, bake absorption, mix time, and loaf volume were all significantly higher for spring than winter wheats. These values were still higher for spring than winter wheats except for test weight when wheat protein content was the co-variate. Both statistical treatments show that hard red spring wheat flour has higher water absorption percent, longer dough mixing requirements, longer dough stability times, and higher loaf volumes than hard red winter wheat flour.Key words: Bread wheat quality, loaf volume, grain protein content, protein quality
