This study evaluates the impact of minimum tillage technology on the yield and quality of winter wheat (Triticum aestivum L.) under the specific pedoclimatic conditions of Poarta Albă, Constanța County, during the 2021–2024 period. The research focused on two cultivars: Katarina and Avenue, grown on areas ranging from 110 to 140 hectares annually, using a conservation tillage system supplemented with irrigation during critical growth stages. Measurements were carried out for plant density, number of grains per spike, thousand-kernel weight, spike weight, test weight, and yield per hectare. Despite annual climatic variability, yields remained high and stable: 8,730 kg/ha for the Avenue cultivar and 8,250 kg/ha for Katarina. Statistical analysis revealed a weak correlation between climatic parameters (temperature, precipitation) and yield, suggesting that minimum tillage technology, combined with irrigation, played a key role in mitigating abiotic stress. The minimum tillage system contributed to water conservation in the soil, reduced erosion, and maintained soil structure, creating a favorable environment for crop development. By minimizing mechanical interventions and protecting the topsoil layer, this technology demonstrated superior agronomic and economic efficiency under conditions of moderate drought. The results support the adoption of this system as a sustainable strategy in regions facing high climatic risk, confirming its role in maintaining both yield and production quality.
