The study analyzes the influence of climate change on the quality of cereal production and crop structure in the Western Plain area. It provides a practical perspective on the adaptability of varieties to pedoclimatic conditions under changing climatic scenarios. The experimental field was established in the Timișoara South microzone, where five key quality parameters were monitored, determining the malting quality of barley and spring barley. The biological material tested included the barley varieties Planet, Daciana, and the barley cultivar Orbiter. The analysis focused on the main quality parameters relevant to industrial processing: average yield, moisture content, protein concentration, and screening fractions. Regarding the quality indices, the protein content ranged from 11.2% to 13.6%, values close to the required standard (9.5–12.5%). The screening fraction < 2.8 mm exceeded 70.0% in most variants analyzed, while the screening fraction < 2.5 mm surpassed 11.0%, showing highly significant results. The sum of the two fractions should represent at least 75–80% of the total sample weight. All varieties showed appropriate indices for the malting industry in terms of production potential and screening percentage an essential indicator of malt quality. The protein content of barley and spring barley grains ranged between 11.5% and 13.6%, indicating the need for further testing to determine the optimal fertilization rate according to the cultivated variety. The cultivated varieties demonstrated significant progress in production potential, stability of quality indices, and good adaptability to climatic stress conditions. In the context of intensified climate change, both barley and spring barley have become increasingly vulnerable to the growing frequency and intensity of extreme weather events, which induce severe forms of abiotic stress throughout the vegetation period.
