Higher corn seeding rates accompanied by improved stress tolerance in hybrids has contributed to incremental yield gains over time. Average corn seeding rates used by growers in the United States and Canada have increased from about 23,000 seeds per acre in 1985 to over 30,000 seeds per acre today, or approximately 300 seeds per acre per year.

During the same time period, average U.S. yields increased from about 105 to nearly 160 bushels per acre, or 2 bushels per acre per year.

Check out this edition of Crop Insights, Optimizing Seeding Rates for Corn Production that discusses hybrid improvements for stress tolerance, current seeding rate trends and optimum seeding rates for corn production.
