The paper presents the results of a field experiment conducted between 2022 and 2025 in the Dobrogea region, under an irrigation system, evaluating the behavior of three maize hybrids (P9911, P9889, and MAS43P) cultivated under a minimum tillage system. The study aimed to assess the influence of the technological itinerary on grain yield, thousand kernel weight (TKW), test weight (TW), plant height, and plant density at harvest. Weed control was achieved through an integrated management system using pre- and post-emergence herbicides (Callisto and Clinic Xpert), in order to reduce weed infestation and preserve soil moisture. The data were statistically analyzed using the ANOVA method, highlighting significant differences among hybrids regarding average yield, which ranged from 7.8 to 9.2 t/ha. Hybrid P9889 showed the highest adaptability and yield stability under irrigated conditions. The combination of minimum tillage, irrigation, and effective weed control contributed to maintaining soil fertility and increasing the energy efficiency of maize cultivation. The results indicate that thermal stress during the May-July period represents the main limiting factor for maize productivity in Dobrogea, even under irrigated conditions, while hybrid-specific adaptability plays a decisive role in ensuring yield stability under increasing climate stress.
