- Intervention effect Early nitrogen applications enhanced ryegrass production.
- Intervention effect Early nitrogen had little effect on clover production by mid March.
- Association Clover percentage and yield decreased as total nitrogen increased.
- Association Ryegrass yield increased with total nitrogen.
- Intervention effect The no nitrogen treatment had the greatest clover percentage.
- Observation Single nitrogen applications usually retained clover above 50%.
- Observation Ryegrass alone yielded 1139 kg ha −1 without nitrogen.
- Intervention effect Ryegrass alone yielded 4038 kg ha −1 with 201 kg N ha −1.
- Observation Three 67 kg N applications were consistently among the most productive treatments.
- Intervention effect The two application mixture equalled ryegrass alone given three applications in yield.
