- Association Residual nitrate did not significantly influence seed oil content.
- Intervention effect N fertilizer increased chlorophyll meter readings at six site-years.
- Observation Sunflower yields varied greatly.
- Association Growing season did not significantly affect yield.
- Association Total precipitation did not significantly affect yield.
- Association Soil moisture at planting did not significantly affect yield.
