Agronomic summary
Occitanie is France's leading sunflower region, particularly Gers (clay-limestone terreforts, boulbenes) and Tarn-et-Garonne. The 1,569 GDD, 307 frost-free days and Mediterranean-influenced climate offer exemplary conditions. LS Forsy, LS Globsun and l-25-02-ios are perfectly calibrated for these soils and the dry late-cycle climate, fully exploiting July–August radiation and heat. Broomrape pressure remains a key concern in some sub-basins.
