- Intervention effect P application did not influence sunflower seed yield.
- Intervention effect P application did not influence sunflower oil content.
- Intervention effect N rates beyond 35 lb/acre did not influence seed yield in 80% of site-years.
- Intervention effect Increasing N significantly reduced percentage seed oil content.
- Association The N–oil relationship statistic was 0.96 for high yield goals.
- Association The N–oil relationship statistic was 0.93 for medium yield goals.
- Association The N–oil relationship statistic was 0.94 for low yield goals.
- Association Residual nitrate did not significantly influence seed yield.
- Intervention effect N fertilizer increased chlorophyll meter readings at six site-years.
- Intervention effect N did not significantly affect yield at sites with higher chlorophyll readings.
- 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.
- Recommendation N and P applications were judged not to produce economic returns in the region.
