Recent studies emphasize optimizing cultivation technologies, particularly planting density, to improve sunflower yield and quality under varying climatic conditions. • Study evaluates the effects of plant density and climate on the yield and quality of two sunflower hybrids, Biloba CLP and SY Daxton, over three growing seasons (2022–2024). • Field trials conducted in the Dnipropetrovsk region revealed that a planting density of 55,000 plants/ha maximized yields for both hybrids across diverse environmental conditions. Lower densities underutilized resources, while higher densities led to excessive competition. • Variability in rainfall and temperature significantly influenced growth stages and yield outcomes. The findings underline the importance of site-specific density optimization and hybrid selection to enhance sunflower production in Ukraine’s agro-climatic zones.
