- Association Dry matter accumulation and grain yield first rose and then fell with phosphorus rate.
- Intervention effect Annual grain yield increased 25.5% with P2 versus P1.
- Intervention effect Annual grain yield increased 31.9% with P3 versus P1.
- Intervention effect Annual grain yield increased 43.8% with P4 versus P1.
- Intervention effect Annual grain yield increased 18.3% with P5 versus P1.
- Intervention effect Phosphorus significantly increased aboveground nitrogen accumulation.
- Intervention effect Phosphorus enhanced crop nitrogen utilization efficiency.
- Intervention effect Grain nitrogen accumulation increased under P2 through P5 versus P1 by 33.5%, 43.4%, 56.1%, and 17.2%, respectively.
- Observation PFP-N under P1 was lower than P2 through P5 by 20.0%, 26.2%, 32.5%, and 17.9%, respectively.
- Observation Soil nitrate did not differ markedly among treatments.
- Observation Soil nitrate was relatively low at harvest for all three crops.
- Observation Nitrogen input minus output was 76.1, -18.2, -50.0, -77.7, and 15.7 kg/hm2 for P1 through P5, respectively.
- Observation Under P2 through P4, nitrogen output exceeded input.
- Recommendation Moderate phosphorus application was concluded to improve nitrogen uptake and use efficiency.
