Other claims from this paper (15)
- Intervention effect Rice N concentration significantly increased with fertilizer across three stages.
- Intervention effect Rice N accumulation significantly increased with fertilizer across three stages.
- Intervention effect P concentration significantly increased with N fertilizer at elongation and heading.
- Intervention effect P accumulation significantly increased with N fertilizer at elongation and heading.
- Intervention effect Excess N fertilizer significantly decreased P accumulation at maturity.
- Intervention effect N uptake rate significantly increased with N fertilizer from sowing to elongation.
- Intervention effect P uptake rate significantly increased with N fertilizer from sowing to elongation.
- Observation N and P uptake rates peaked at 225.0 kg ha 1 during heading to maturity.
- Intervention effect N grain-yield use efficiency significantly decreased with increasing N fertilizer.
- Intervention effect P grain-yield use efficiency significantly decreased with increasing N fertilizer except at 337.5 kg ha 1.
- Observation N and P harvest indices followed a parabolic pattern with maximum at 262.5 kg ha 1 N.
- Association N and P uptake and utilization were significantly synergistic across rice growth.
- Association Rice yield was significantly correlated with N/P accumulation before heading.
- Association Rice yield was significantly correlated with N/P uptake rate before heading.
- Recommendation Authors conclude excess N fertilizer may fail to increase or decrease N and P uptake and utilization.
