The aim of the study was to analyze the effect of different amounts of nitrogen on seed yield and quality of selected varieties with different length of vegetation period, specific grain characteristics, and from different breeding Institutes. Trials were conducted on chernozem soil type on the experimental field of Maize Research Institute Zemun Polje (Serbia). Based on the results obtained it can be concluded that all fertilization variants increased the seed yield from 3.6% (P60K60 variant) to 12.2% (N90P60K60 variant). Fertilization variants had lower positive effect by increasing the seed protein content and was from 0.4% (P60K60 variant) to 4.0% (N90P60K60 variant). Negative correlation between seed protein and oil content was determined.
