The greatest weight of the above-groud parts in young winter wheat plants was obtained with plants fertilized with the variant NPK in which phosphorus and potassium were applied regularly every year and with plants fertilized with the increased quantity of phosphorus 5 years in advance. The variant in which the increased quality of phosphorus was applied for 5-year supply, produced the best effects concerning the nitrogen content. The contents of phosphorus and potassium were the highest with plants of the NPK variant, fertilized with phosphorus and potassium regularly every year. In the case of the potassium content, the NPK variant in which phosphorus and potassium were applied for the 5-year supply was the most prominent.
