Optimum Seeding Rate by Yield Level
Figure 2. Corn yield response to population and optimum economic seeding rate by location yield level at water-limited sites, 7-yr average. (Averaged across all hybrids tested. Economic optimums based on a corn grain price of $3.50/bu and a seed cost of $3.00 per 1,000 seeds; assumes 5% overplant to achieve target population.)
