Abstract :
Khorasan wheat (Triticum turgidum L. ssp. turanicum Jakubz.) the white awn population is the optional type of a high-energy grain. This study aimed to examine the influence of plants’ mineral nutrition on the chemical composition of Khorasan grain. The mineral diet used in the supplementary plant nutrition affected the total amount of dry matter and the chemical composition of wheat grains, increasing its nutritional value. At the time of harvest, Khorasan wheat grains contained 89.74% of dry matter, i.e. 10.26% of water, while in the variants with additional nutrition had less dry matter 86.90% and more water, 13.10%, which indicates an extension of the vegetation period of plants in conditions of enhanced mineral nutrition. Mineral nutrition, which primarily increased the amount of nitrogen, statistically significantly affected protein synthesis in plants. Khorasan wheat grains had 14.94% of total proteins in the control and 15.2% in variants with NPP nutrition. Plant nutrition did not have a greater impact on the synthesis of oils in the grains, starch, NFE, and mineral salts content. The supplementary nutrition affected the total amount of dry matter and chemical composition of wheat grain increasing its nutritional value.
