Full Text:

Abstract

The results of researches on study of efficiency of mineral fertilizers application at cultivation of spring wheat on light loamy soil are given in the article The basic application N60P60K120 and top dressing by nitrogen in a doze of 30 kg/hа in a phase of first unit has ensured the maximal yield of a grain 68,2 c/hа. The most qualitative grain is obtained in a variant with split application N60+30+30 against application P60K120: the protein content in spring wheat grain has made 12,0%. The sum critical amino acid - 10,17 g/kg of a grain, irreplaceable - 36,24 g/kg of a grain.
