Agronomic summary
Corsica meets excellent conditions for castor bean: 2,268 GDD comfortably cover the thermal needs (130–200 day cycle), the long frost-free season (347 days) secures full maturation, and loamy soils at pH 7 suit the crop perfectly. LS Marilou (giant castor), LS Suzi (semi-dwarf) and LS Peter (dwarf) can diversify the island's value chains by valorising difficult lands or experimental rotations on the eastern coast.
