Agronomic summary
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.
