- Intervention effect Close cutting increased crude protein yield of mixed herbage.
- Intervention effect Close cutting increased clover dry matter and crude protein yields.
- Observation Clover response to cutting height developed more slowly and was modified later by fertilizer nitrogen.
- Mechanism The authors suggest close cutting increased yield through differential stem and leaf formation in grasses.
- Mechanism Different cutting frequencies probably explain discrepancies with earlier cutting height studies.
- Intervention effect Delaying the first small nitrogen dressing reduced mixed herbage dry matter and crude protein yields.
- Intervention effect At low total nitrogen, delaying first dressing had little effect on clover yields.
- Intervention effect At heavier nitrogen, delaying first dressing reduced mixed herbage dry matter yield.
- Intervention effect At heavier nitrogen, delayed dressing slightly increased clover dry matter and protein yields.
- Intervention effect Under heavy nitrogen, delayed dressing reduced mixed herbage crude protein only when it lowered season total nitrogen.
- Intervention effect Delaying first dressing made seasonal production more uniform.
