France Corn Crop Seen at 8.1 Million Tonnes, Lowest Since 1980

France's 2026 grain corn crop is expected to fall to 8.1 million tonnes, the lowest level since 1980, after repeated summer heatwaves cut both harvested area and yields.

Agreste, the statistical service of the French agriculture ministry, estimates production will decline 42 percent from 2025.

The fall reflects a 26 percent reduction in the area ultimately harvested for grain and a 21 percent decline in average yield as heat and drought stressed spring and summer crops.

Average grain corn yield is estimated at 68.2 quintals per hectare, with some planted area converted to silage rather than taken through to grain harvest.

The September estimate marks a further deterioration from Agreste's August projection of 9.0 million tonnes, showing how weather conditions continued to damage the crop through the summer.

The decline matters beyond French farms because France is one of the European Union's major grain producers and changes in domestic corn availability can affect feed markets, imports and regional price relationships.

Other spring and summer crops were also affected by the extreme weather, including sunflower and potatoes, while winter cereals were relatively less exposed to the same heat pattern.

For livestock feeders and grain traders, the key question is how much of the production shortfall is offset by imports, alternative feed grains and changes in demand during the 2026 to 2027 marketing season.
