- Intervention effect At 35/25°C, nitrogen deposition increased E. crusgalli shoot biomass by 29.18%.
- Intervention effect At 35/25°C, nitrogen deposition increased rice shoot biomass by 27.80%.
- Intervention effect At 35/25°C, nitrogen deposition increased weed nitrogen uptake by 87.33%.
- Intervention effect At 35/25°C, nitrogen deposition increased weed phosphorus uptake by 49.73%.
- Intervention effect At 35/25°C, rice nitrogen and phosphorus uptake showed no change.
- Intervention effect At 30/20°C, nitrogen deposition increased weed shoot biomass by 48.99%, 72.68% and 36.18% at three doses.
- Intervention effect At 30/20°C, nitrogen deposition increased weed tiller number by 111.11%, 122.22% and 144.44%.
- Intervention effect At 30/20°C, nitrogen deposition increased weed shoot nitrogen uptake by 108.88%, 129.22% and 134.29%.
- Intervention effect At 30/20°C, nitrogen deposition increased weed shoot phosphorus uptake by 16.53%, 65.05% and 22.47%.
- Intervention effect At 30/20°C, the same nitrogen depositions did not change measured rice traits.
- Intervention effect Nitrogen deposition significantly increased weed-to-rice shoot biomass ratio at 30/20°C.
- Mechanism Authors infer nitrogen deposition may increase weed competition over rice, especially at lower temperature.
