The aim of this study was to analyse e the effect of variety, nitrogen rate and type and their interaction on protein content and to determine the economic feasibility of varieties and fertilizer application for the highest values. The subject of the experiment consisted in testing during two wheat growing seasons 2021-2023, twenty-seven winter wheat varieties fertilized with nitric and ammoniacal nitrogen in three different rates - 120, 150 and 170 kg N ha-1. The layout of the experimental plan was done using stratified randomization block method. Cultivars were factorially combined and arranged in completely randomized blocks. We concluded that compared with the mean of the experience of 14.75%, variety and nitrogen fertilization systems interaction had a significant effect on wheat protein content. The highest protein content was obtained by the Tika Taka variety - 15.78%. Regarding the fertilization system, with very significant differences the values above the average of the experience, 15.32%, 15.27% and 15.36% were obtained the levels of fertilization with nitric nitrogen and those with ammoniacal nitrogen had negative values of 14.04%, 14.20% and 14.32%.
