The aim of this study was to analyse the effect of wheat variety, nitrogen fertilizer rate and type and their interaction on protein content and to determine the economic feasibility of application the fertilizer and varieties, two key drivers that contribute guiding the future with efficient agronomic practices to guarantee wheat quality in the advent of the most significant changes for agriculture. The subject of the experiment consisted in testing during one wheat growing season, twenty-seven modern winter wheat varieties fertilized with nitric and ammoniacal nitrogen in three different rates - 120, 150 and 170 kg N ha-1 active substance. The biological material is represented by 27 romanian and foreign autumn wheat varieties, some of the most cultivated wheat varieties in the Western Plain of Romania, and the criteria that were the basis of their choice are the high production potential, the high tolerance to disease attack and pests and specific qualities for milling and baking. This study reflects the results obtained in the research Laboratory for seed quality control at the University of Life Sciences “King Mihai I” from Timișoara, using the standard method with a whole seed NIR multiparameter analyzer using near-infrared transmission (transmittance) technology. the experience average for protein content was 12.94%. In the case of cultivars, there were no differences from the field average. As for agricultural funds, the highest value was obtained at the fertilization level of 170 kg ha-1 a.s. ammoniacal nitrogen of 13.79%, and the lowest at the fertilization level of 120 kg ha-1 a.s. nitric nitrogen of 12.11. The other agricultural funds did not show differences. Even in the case of the variety-agricultural interaction, there were no statistically guaranteed differences.
