For obtaining the optimal and qualitative grain yield, to plant should used such mineral fertilizers application rates that would be able to provide also maximal total protein content and the high economical indicators. In the turf-podzol soils, optimal nitrogen mineral fertilizers application rate for spring barley was 60 kg haE-1 that by optimal phosphorus and potassium application gives yield of barley 'Rasa' - 3.77 t haE-1 and the netto income - 25.09 Ls haE-1.
