The aim of the study was to track the change in the values of some technological and biochemical parameters under the influence of prolonged application of synthetic nitrogen, phosphorus and potassium. The experiment was conducted in the experimental field of the Field Crops Institute-Chirpan, Bulgaria. The study showed data from 2020/2024. The results of the study showed that meteorological conditions strongly influenced the biochemical traits and to a small extent on the technological parameters. Nitrogen fertilization had a major impact on the technological and biochemical traits of durum wheat compared to phosphorus and potassium fertilizers. High nitrogen rates strongly influenced biochemical traits,
while moderate fertilization was more effective for technological parameters. Average for the test period, fertilization with N80P120 increased thousand kernel weight (47.1 g) to the greatest extent. Combined fertilization with N40P40 had the strongest effect on test weight (78.5 kg/hl). Grain vitreousness and protein content were highest under the influence of N160 (75.6% and 15.2%). Gluten content was maximized by fertilization with N160P40 (32.3%).
