Other claims from this paper (6)
- Observation Light-limited grass dry matter production rises exponentially until canopy closure.
- Observation Grass production subsequently decreases and reaches zero.
- Mechanism Increasing respiration relative to photosynthesis partly explains declining grass production.
- Observation Grass organic constituents remain fairly constant across the season under optimal water and nutrients at a given growth stage.
- Recommendation Harvesting grass with higher sugar and lower protein is proposed to improve rumen digestion and sward regrowth.
- Observation Selection is considered unlikely to combine high reserve level with high production rate in one strain.
