15 adapted varieties
In Normandie, the local agronomic conditions (Cfb — oceanic temperate climate, 965 growing degree days, silty clay loam soil at pH 6.6, 293 frost-free days) are particularly favorable to sunflower cultivation.
Favorable growing period: May to October.
Recommended varieties: LS SKIPPY, L 15-13 OS – BLUEBIRD, L 25-02 IOS

Key agronomic watchpoints in this zone:
Normandy (silt over chalk on the Caen Plain, Augeron bocage, Cotentin schists) is a marginal zone for sunflower, dominated by dairy farming, silage maize and fibre flax. The 965 GDD and 293 frost-free days make cultivation technically feasible with ultra-early varieties (LS Bajkalia, L-15-13-OS Bluebird, L-25-02-IOS), targeted at the best-drained plots in Eure and Calvados. The moderate summer water deficit (-228 mm) remains manageable thanks to summer rainfall.
The varieties recommended above are pre-selected based on local climate, soil and disease pressure. Top picks combine adapted maturity, yield stability and the specific disease tolerances needed in Normandie.
The favorable sowing window is typically from May to October. Exact timing depends on soil temperature (>10°C at 5 cm), weather forecast and your local agronomist's advice.
Yields depend on variety, agronomic management and the season. Under typical Normandie conditions with good practices, our adapted varieties target stable, competitive commercial yields. Precise ranges are available on request.
