The National Corn Growers Association yield contest produced a national winner above 600 bushels per acre, with 27 national winners averaging over 376 bushels per acre. State winners in the upper Midwest exceeded 300 bushels per acre even though the year began in drought.
Contest yields are cherry-picked plots and do not change the commercial crop estimate, so the price effect is minimal, though they signal genetic yield potential.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
