- Association Residual nitrate did not significantly influence seed yield.
- Association Residual nitrate did not significantly influence seed oil content.
- 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.
- Association Growing season did not significantly affect yield.
