Other claims from this paper (8)
- Intervention effect A 60–70% ammonium mixture yielded the highest nitrogen uptake.
- Intervention effect Rice absorbed 131~145% more nitrogen at 10.0 mM than 1.0 mM.
- Intervention effect Accumulated nitrogen was nearly the same at both nitrogen concentrations.
- Observation Tongil cultivars produced more dry matter than japonica cultivars.
- Observation Tongil cultivars accumulated more nitrogen than japonica cultivars.
- Observation Nitrogen recovery was 90.8-99.0% in low concentration solution.
- Observation Nitrogen recovery was 69.4-81.7% in high concentration solution.
- Recommendation The authors recommend steady low-concentration nitrogen supply to prevent nitrogen loss without reducing growth.
