Top-dressing treatment of spring barley to modify its quality

New barley products can be developed by modifying the content of bioactive components in grain through breeding, as well improving its quality at lower fertilizer costs. We aimed to study effects genotype, growth conditions, and top-dressing application nitrogen organo-mineral fertilizers on chemical composition grain.
 The varieties Novichok, Rodnik Prikamya, Pamyaty Rodinoy were grown under normal (2020) dry (2021) field conditions. plants top-dressed with mineral (CAS; SpetsKhimAgro, Kirovo-Chepetsk, Russia) or (Amino Start Alfastim; Polydon® Agro, Moscow, tillering heading phases. contents protein, starch, fat, crude fiber analyzed an INFRAMATIC 8620 instrument (Perten Instruments, Stockholm, Sweden).
 CAS reduced 4.5–8.3% (Novichok) during drought increased starch 2.1% (Novichok), 14.2% (Rodnik Prikamya), fat 18.9% (Pamyaty Rodinoy) humidity. Amino applied conditions 2.9% protein 7.8–8.9% 14.4 6.3%, respectively, but 5.1% Rodinoy. Alfastim 10.7% it 3.6–7.2% other cultivars. It also 22.8% decreased 18.6% Finally, this 12.7% 9.8% In drought, 5.2–12.2% Prikamya Rodinoy.
 Top-dressing modify (up 10.4% fiber, 3.6% 7.5% fat), depending consumer’s requirements.
