Effect of storage time and Furolan on the contents of nitrogen, protein and non protein nitrogen in winter wheat grain

Abstract

This study was carried out to investigate the effect of storage time and growth regulator, Furolan on protein, non-protein nitrogen and nitrogen contents of three varieties of winter wheat grains namely Batko, Diya and Krasnodar 99. The contents of the nitrogen, protein and non-protein nitrogen in winter wheat grain were determined by different protocols during the full ripeness phase of the grain and the period of 12 months storage. The grains (both the control and experimental) were kept in storage for varied periods under normal conditions. Krasnodar 99 variety responded most to the Furolan and recorded an increase in protein nitrogen content by 46.3% followed by 24.9% in experimental Batko variety and 17.4% in Diya’s variety in comparison with the control. The content of protein nitrogen in the grain of experimental Batko variety increased up to the seventh month of storage, and then decreased by the 12th month of storage. In the control—a similar tendency of change in this parameter was observed. It was noted that seven months of storage is critical in change dynamics of the content of non-protein nitrogen in the selected winter wheat varieties studied.
