IDEAL STANDS MAXIMIZE YIELD POTENTIAL
Picket fence corn stands – those that are exactingly uniform, have the most potential to produce maximum yields. Even spacing and emergence are of critical importance to maximizing yields. How fast you pull the planter across the field has a significant influence on planter performance and the resulting uniformity of the seed planted.
Planters equipped with new technology and after-market equipment greatly improve factors including seed metering performance, however traveling too fast may make those costly technologies ineffective. The faster you’re moving, the greater the inertia. That means seeds may roll or bounce. Negative results including poor seed-to-soil contact, poor seed spacing, and inaccurate seeding depth may result.
Mississippi State University research shows the corn yield response to planter speed comparison (graph). Consider that at 4 mph, you are dropping about 15 seeds per second per planter unit. Each mile per hour increases distance covered by 18-inches per second. AgVenture encourages growers to slow down to improve stand uniformity.
