The western leg of the 2026 Pro Farmer Crop Tour reported Nebraska corn in generally good condition, with an estimated average yield of 172.9 bushels per acre, though disease, heat damage and pollination problems were noted. South Dakota crops showed greater variability after a cold snap followed by hot, dry weather, with corn denting and maturing earlier than usual.
Heat, dryness and crop disease can reduce yields and tighten U.S. corn supplies, while Nebraska’s relatively sound crop may offset some losses. The mixed field reports are a modest bullish risk for corn prices, but the text gives no indication of a major production shock.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
