Other claims from this paper (10)
- Intervention effect The CRFIII treatment gave grain yield 13.15% higher than the CCF treatment.
- Intervention effect The SCFIII treatment gave grain yield 14.15% higher than the CCF treatment.
- Intervention effect The CRFII treatment gave grain yield 9.69% higher than the CCF treatment.
- Intervention effect The SCFII treatment gave grain yield 10.04% higher than the CCF treatment.
- Intervention effect Grain yield did not differ significantly among the CRFI, SCFI and CCF treatments.
- Intervention effect The CRF treatment significantly lowered ammonia volatilisation rates compared with CCF.
- Intervention effect After anthesis, CRF-treated maize had a higher net photosynthetic rate than CCF-treated maize.
- Intervention effect Agronomic NUE and apparent N recovery were higher in the CRF treatment than in the CCF treatment.
- Intervention effect N uptake and physiological NUE were higher in the four yield-enhanced CRF treatments than in CCF.
- Mechanism The NUE increase under CRF is attributed to a higher photosynthetic rate and lower ammonia volatilisation.
