Other claims from this paper (14)
- Intervention effect Nitrogen increased leaf primordia on young Italian ryegrass tillers.
- Intervention effect Longer uninterrupted growth of parent tillers appeared to increase leaf primordia.
- Intervention effect Increasing harvest interval from 3 to 10 weeks approximately halved emerged leaves over 30 weeks.
- Intervention effect Nitrogen did not affect the number of leaves that emerged.
- Intervention effect Increasing harvest interval from 3 to 5 weeks at least doubled leaf deaths.
- Observation The second and third leaves had longer potential lives than the first.
- Intervention effect Longer harvest intervals greatly increased average age of green canopy leaves at harvest.
- Intervention effect Nitrogen and longer harvest intervals increased length and width of green leaf blades.
- Intervention effect Green leaf blade thickness did not increase with nitrogen or longer harvest intervals.
- Intervention effect Nitrogen-induced increases in tillers and leaves mattered at shorter intervals.
- Intervention effect Applied nitrogen reduced dry weight per unit plant tissue volume.
- Intervention effect Applied nitrogen increased stem length.
- Intervention effect Applied nitrogen increased herbage weight and volume per unit canopy volume.
- Observation Exposed stem surface appeared too large to ignore in assessing canopy photosynthesis, especially at longer intervals.
