e1“W1 combined with 100 kg·hm -2 nitrogen application (W1N2) significantly increased carbon and nitrogen concentrations in leaves and stems and promoted the translocation of carbon and nitrogen to pods. The leaf and stem C/N ratios remained optimal (16.18 to 32.18 and 13.11 to 31.77). The nitrogen nutrition index (NNI) of the W1N2 treatment remained close to 1 throughout the growth, indicating balanced N supply. Soil CO…” Show full quote

- Observation Cumulative ammonia volatilization peaked on the third day after fertilization.
- Association Cumulative ammonia volatilization rose with nitrogen rate.
- Intervention effect Regulated deficit irrigation reduced ammonia volatilization at equivalent nitrogen levels.
- Intervention effect W1N2 significantly increased leaf and stem carbon and nitrogen concentrations.
- Intervention effect W1N2 promoted carbon and nitrogen translocation to pods.
- Observation Leaf and stem carbon to nitrogen ratios remained in the reported optimal ranges.
- Observation Soil carbon dioxide emission flux peaked at flowering.
- Intervention effect W1 reduced average and cumulative carbon dioxide emissions across stages.
- Association Higher nitrogen rates increased carbon dioxide emissions.
- Observation All treatment combinations were carbon sinks.
- Intervention effect W1N2 had the highest net ecosystem productivity, 140.3% to 154.3% above W0N0.
- Intervention effect W1N2 produced maximum yields of 5850.08 to 5930.88 kg per hectare.
