Ask The Agronomist: Stress Wheel Research
Stress Wheel Overview
In our Stress Wheel Plot, we study plant response and ear flex in 38 hybrids different hybrids. Resembling a pinwheel, corn is planted from the outside to the center with varying populations starting with 15,000 plants per acre (PPA) and increasing to 60,000 PPA.
We have featured 24 hybrids and identified the following for each:
- Ear Type
- Population Spread from 60,000 PPA to 15,000 PPA
- Visual cross sections (kernel depth)
