Other claims from this paper (11)
- Intervention effect Stem diameter growth increased by 4% to 32% with increased irrigation.
- Association Irrigation was inversely related to foliar nitrogen content.
- Intervention effect Irrigation had no effect on foliar phosphorus, potassium, magnesium and manganese.
- Intervention effect Irrigation increased foliar calcium.
- Observation Approximately 2.0% to 4.5% of applied nitrogen was lost through leaching.
- Mechanism High irrigation increased total biomass through greater root and stem biomass.
- Intervention effect Higher irrigation increased nitrogen use efficiency and assimilatory nitrogen use efficiency.
- Mechanism Higher irrigation may raise nitrogen use efficiency through increased carbon assimilation and net primary productivity.
- Intervention effect Irrigation had no clear effect on root weight ratio.
- Intervention effect The lowest irrigation gave a higher index of nitrogen availability per unit foliage.
- Mechanism Under water stress, nutrient supply to organs may buffer reduced assimilation and nitrogen use efficiency.
