Other claims from this paper (9)
- Observation Leaf mass followed logistic trends with upper asymptotes of 50 to 225 g m −2 by rate and season.
- Observation Stem mass lagged leaf mass by 7 to 14 days.
- Observation Stem mass reached 75 to 300 g m −2 by day 28.
- Intervention effect Increasing nitrogen rate increased summer tiller mass from 1.5 to 3 g per tiller.
- Intervention effect Increasing nitrogen rate increased autumn tiller mass from 1 to 1.5 g per tiller.
- Observation Leaf to stem ratio increased to 1.0 within 14 to 21 days.
- Observation Leaf to stem ratio subsequently decreased.
- Intervention effect Nitrogen fertilization did not affect rhizome and root mass.
- Intervention effect Nitrogen beyond 90 kg N ha −1 per regrowth period did not enhance regrowth.
