SCIENTIFIC FOUNDATIONS OF NITROGEN AND FOLIAR FERTILIZATION IN IMPROVING WINTER WHEAT YIELD AND GRAIN QUALITY

winter wheat, yield, nitrogen fertilization, foliar feeding, protein, gluten, grain quality, innovative technologies.Abstract
This article extensively discusses the role of nitrogen fertilization and foliar feeding in enhancing winter wheat production under the conditions of Uzbekistan. Field experiments revealed that the application of nitrogen fertilizer three times increased grain yield to 72 c/ha. Simultaneously, protein content rose to 14.3% and gluten to 30.3%, leading to a substantial improvement in grain quality. Foliar application of carbamide solutions enabled yields of up to 71.7 c/ha. Moreover, protein levels increased to 13.8% and gluten to 29.5%, thereby ensuring superior grain quality. These findings indicate that integrating root fertilization with foliar feeding creates a comprehensive approach to improving both yield and quality indicators in winter wheat cultivation.
