12 adapted varieties
In Grand Est, the local agronomic conditions (Cfb — oceanic temperate climate, 927 growing degree days, silty clay loam soil at pH 7, 248 frost-free days) allow corn cultivation.
Favorable growing period: May to September.
Recommended varieties: LS Marelia, ZETA 105, ZETA 115 S
Limited growing degree days (927 GDD). Choose the earliest maturing varieties.
Notable summer water deficit (-294 mm). Pick drought-tolerant varieties.
Long frost-free season (248 days), allowing broad crop cycles.
Favorable growing period: May to September.
Neutral pH (7), suitable for most crops.
Ultra early hybrid with fast dry down, strong density tolerance and excellent digestibility.
Ultra-early hybrid with ultra-short cycle, rapid dry-down, and strong performance under dense planting.
Ultra-early hybrid with a very short cycle, rapid maturity, strong density adaptation and excellent feeding quality.
Ultra-early hybrid with a very short cycle, rapid dry down, and strong digestibility.
Ultra-early hybrid with ultra-fast dry-down, strong density adaptation and excellent forage digestibility.
Ultra-early hybrid with a very short cycle, fast dry-down, strong density adaptation and excellent grain-to-precocity ratio.

Ultra-early corn hybrid offering very fast dry down and excellent digestibility.
Ultra-early hybrid with a very short cycle, ideal for early silage and fast grain maturity.
Ultra-early double-cross hybrid suited for catch cropping, high densities and strong digestibility.
Key agronomic watchpoints in this zone:
Grain maize is important in the Alsace plain (fertile loess, warm semi-continental climate) and progresses in Lorraine. The 927 regional GDD impose ultra-earlies (LS Marelia, ZETA 105, LS Bajkalia FAO 120) for rainfed grain, except in Alsace where mid-earlies are accessible. Irrigation is a major asset given the deficit (-294 mm). Silage remains competitive in Lorraine livestock zones.
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 Grand Est.
The favorable sowing window is typically from May to September. 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 Grand Est conditions with good practices, our adapted varieties target stable, competitive commercial yields. Precise ranges are available on request.
