What aggregated community data CANNOT tell you:
Aggregated community data can be a useful supplement to research data for making seeding rate decisions; however, IT IS NOT A VIABLE SUBSTITUTE for controlled-trial data in characterizing genetic differences in plant population response. |
Figure 2. Corn yield response to population and optimum economic seeding rate by location yield level, 2009-2015.
Averaged across all hybrids tested. Economic optimums based on a corn grain price of $4.00/bu and a seed cost of $3.00 per 1,000 seeds; assumes 5% overplant to achieve target population.
