The main objective study was to evaluate the efficiency of fertilizer phosphorus - single superphosphate two blends (4-17-24 and 6-16-26) and complex fertilizer: 6-20-30. The highest yielding efficiency was found for the blending 4-17-24 and the complex fertilizer 6-20-30. Wheat fertilized with the 4-17-24 developed the highest number of ears and grains per ear. The high yielding effect of both fertilizers can be explained by their main chemical component, i.e. ammonium phosphate. The study aldo showed that phosphorus of high yielding winter wheat crop should take into account its nutritional requirements, even when cultivated soils are rich in available phosphorus
