Abstract
In article the results of research of influence of mineral fertilizers on quality of oats grain at cultivation on luvisol loamy sand soil are resulted. The application of fertilizer system P40K90 +60+30 Cu + Mn + fungicide has provided reception of 48,7 c/ha grain, thus fiber gathering made 5,9 c/ha, the protein content in grain - 14,1%. By application of mineral fertilizers in such combination and fungicide promoted increase in the sum of irreplaceable amino acids at 20,4%, and critical - on 18,1% in comparison with a variant without fertilizers. «Amino acid speed» on irreplaceable amino acids makes 103,3%, on critical - 85,0% from the norms, recommended by FАО/WHO, «chemical number» - 80,55% and 64,0% accordingly. The further increase in a dose of nitrogen reduces biological value of fiber.
