Effect of late nitrogen nutrition on formation of harvest elements, grain yield, and quality indicators of winter wheat
It is known that almost 50% of winter wheat harvest is due to mineral fertilizers. Among mineral fertilizers, nitrogenous fertilizers are of special importance. The plant’s response to nitrogen fertilizers starts from the initial stages of plant development and continues until the ripening stage. Ni...

| description | It is known that almost 50% of winter wheat harvest is due to mineral fertilizers. Among mineral fertilizers, nitrogenous fertilizers are of special importance. The plant’s response to nitrogen fertilizers starts from the initial stages of plant development and continues until the ripening stage. Nitrogen is involved in all physiological processes in the plant. Nitrogen fertilizers differ from other types of macro fertilizers in their mobility. These fertilizers have a quick effect on the plant and are easily absorbed by the plant. There are different opinions about winter wheat fertilization. Some experts believe that the annual rate of nitrogen fertilizers should be applied in the early stages of development, in early spring. Other authors state that nitrogen fertilization is necessary two or three times during the season. In the experiment, a relatively low indicator of grain yield was observed in the control option of 35 q/ha, and the highest indicator was 72 q/ha in the triple-fed option. In the experiment, additional nitrogen fertilization provided an additional grain yield of 21-37 q/ha of winter wheat. The highest results for all quality indicators of grain were recorded in conditions where nitrogen fertilizer was applied at the rate of 80+80+40 kg/ha three times during the growing season. In this variant, the grain transparency was 90%, the protein content was 14.3%, and the gluten content was 30.3%. |
