University of Nebraska researchers report disappointing 2025 corn yields in parts of the state, with 20-40 bushel per acre shortfalls in areas such as York/Seward and west-central Nebraska. Leaf and stalk rot pathogens, high nighttime temperatures, storm damage, and over-irrigation were cited as causes.
Regional yield losses in Nebraska tighten local corn supply somewhat, but the impact on national prices is modest given the record national crop.
After 56 past bullish disease events, Corn moved a median -0.1% over 5 sessions (48% higher; middle half -1.5% to +1.6%), and +0.8% over 20.
