The paper analyzes the results of an international stationary field trial (ISDV) in which corn was fertilized with increasing doses of nitrogen (0-270 kg N/ha). The trial was established on the calcareous chernozem soil, at the Rimski Sancevi experimental field of the Institute of Field and Vegetable Crops in Novi Sad, Serbia (Yugoslavia). The analysis covers a period of 18 years or six rotations. Corn was grown in a three-crop rotation, after wheat and before spring barley, i.e., in a 100% cereal rotation. The main conclusion was that the applied nitrogen doses significantly affected the yields of corn, but only to the level of 110 kg N/ha. The control rendered the average yield of 9.61 t/ha or 80% of the maximum yield. The increase in nitrogen content was linear with increases in nitrogen dose, in grain, harvest residues and the entire plant. Nitrogen removal by grain, harvest residues and the total yield also increased with increases in nitrogen dose, but following regression curve. Significant interaction was found between the weather conditions during the experiment and the realized yield, i.e., the effect of the nitrogen doses under study.
