The purpose of this study is based of assessing the influence of leaf fertilizers on the two common wheat varieties. The fertilization was started with the liquid fertilizers Lactifrost, Lactofol base and Wuxal Grano. These are leafy liquid fertilizers that are used to nourish crops. A basic fertilization with ammonium nitrate was also carried out. The study options are as follows: 1. Without fertilization; 2. Ammonium nitrate (N14); 3. Lactifrost - l l/da; 4. Lactifrost + Lactofol base - 1.0 l/da + 0.5 l/da; 5. Lactofol base - 0.5 l/da .; 6. Wuxal Grano – 0.400 l/da; 7. Wuxal Grano - 0.400 l/da + 0.200 l/da. The results of study show that the crude protein content ranges from 128.50-143.94 g/kg DM in the Enola variety and from 115.93 to 127.34 g/kg DM in the Illico variety. The introduction of Wuxal Grano slurry increased the crude protein content by 9.1 and 12.0% relative to the control. As a result of the correlation analysis, a very high correlation (r = 0.947-0.993) was found between CP and PDI for both common wheat varieties.
