How to interpret the 2025 value
USDA NASS reported a final 2025 U.S. average corn grain yield of 186.5 bushels per acre. Because corn uses 56 lb per bushel, that equals about 10,444 lb per acre before local moisture, grade or contract adjustments.
For broader crop comparisons, use the U.S. crop yield per acre table. For crop-specific weights, use the bushel weight by crop table.
