This paper aims to analyze the influence of chemical fertilization on the quality indices of wheat (Triticum aestivum L.) under the specific pedoclimatic conditions of Timiș County, an important agricultural region in western Romania. The study was conducted over two agricultural years, using the autumn wheat variety, cultivated on chernozem soil, under the influence of a moderately continental climate with Mediterranean influences. Differentiated doses of mineral fertilizers based on nitrogen (N), phosphorus (P), and potassium (K) were applied in various combinations and at different growth stages. The analyzed parameters included protein content, test weight (hectoliter mass), gluten content, amino acid profile, and protein quality—key indicators of wheat quality for baking purposes. The results showed a significant positive correlation between nitrogen fertilization and the increase in protein and gluten content; however, they also revealed potential reductions in test weight in cases of excessive nitrogen application. Furthermore, it was found that a balanced application of NPK led to superior production quality, with visible effects on the technological value of the wheat. The conclusions of the study emphasize the importance of adjusting fertilizer doses according to soil characteristics and local climatic conditions, in order to achieve an optimal balance between yield quantity and quality. The results may serve as a practical guide for farmers and agronomy specialists in the western region of the country.
