In the specific zonal pedo-climatic conditions, as well as the changes in local microclimates related to global warming, the modifications in cultivation technologies are important factors that have a significant impact on modern agriculture. The paper presents the results of research on the behaviour of three sunflower hybrids when cultivated in two basic tillage systems, in the pedoclimatic conditions of the Northern Bărăgan area. The implementation of new agricultural practices requires a longer period of research on the effects of basic soil operations on sunflower production and quality indicators. In the current pedoclimatic conditions of Unirea area, located in the Northern Bărăgan Plain where the experiments were conducted, the practice of basic soil operations, specifically ploughing to a depth of 30 cm, ensures higher yields with slightly improved quality indices. Additionally, the hybrids used in this study exhibited different responses to the two cultivation technologies employed. The research found that sunflowers react favourably to both classical and minimum tillage technologies. These technological changes aim to reduce the damage to the soil's structure and quality, manage resources efficiently, and reduce the environmental impact. The research results have theoretical and practical importance, revealing the significance of applied cultivation technologies in protecting the environment and soil, as well as reducing the costs associated with seed drying.
