On well cultivated sod-podzolic light loamy soils at the average level of the manure application in a crop rotation 10 t/ha in an interval of soil acidity degree 5,5-5,7 - 6,3-6,5 on the bachground P60 K120 on the average under spring wheat yield (45,9-48,3 c/ha) is more effectively the dose N60 in the main application. It is permitted to regulate nitrogen top-dressing dose in the phase of beginning of leaf-tube formation using the developed diagnostic scale on the total nitrogen content in plants. Oscillations of gluten content in spring wheat grain from 18 to 31 % are determined in considerable measure by interaction of nitrogen fertilizers with weather conditions
