Other claims from this paper (7)
- Intervention effect Sward dry matter production increased with cutting height.
- Intervention effect Sward dry matter production increased with the interval between defoliations.
- Intervention effect Defoliation did not change the grass to legume proportion.
- Association Defoliation effects on dry matter production resembled estimates from integrated canopy photosynthesis.
- Intervention effect Defoliation height and frequency did not affect leaf photosynthetic characteristics overall.
- Observation Leaf photosynthetic rates appeared depressed during the first one to two weeks after defoliation.
- Mechanism Defoliation effects on dry matter production operated mainly through leaf area index and light interception.
