The analysis of the study of nitrogen, phosphorus and potassium content in spring wheat in the tillering – full ripeness phases was carried out. It is revealed that the maximum content of these macronutrients is observed in the initial phases of culture development and with the onset of subsequent phases decreases several times relative to the tillering phase. This is due to the intensive outflow into the reproductive organs, which is very important in the formation of a full- fledged high-protein grain of spring wheat. On average, during the growing season, the accumulation of nitrogen, phosphorus and potassium in plant samples of soft wheat is higher than in hard wheat. The highest yield of soft wheat was shown by the lines 1799(14) and 2905(14), which exceeded the standard for nitrogen accumulation. In durum wheat, cultivar 926(15) was the best in terms of yield, which was the best in terms of nitrogen and potassium accumulation on average over the entire growing season
