- Observation Reduced nitrogen had no net loss before and around anthesis.
- Observation Protease activity was low around anthesis.
- Observation Nitrogen loss rose at later stages.
- Association Protease activity rose at later stages alongside nitrogen loss.
- Observation Flag and penultimate leaf nitrogen concentrations exceeded third-leaf values significantly.
- Observation Protease activity at pH 4 differed significantly among leaf blades.
- Observation At pH 7, flag and penultimate blade protease activities did not differ significantly.
- Observation Protease activity ranked flag above penultimate above third blade.
- Intervention effect Soil nitrogen significantly increased leaf-blade nitrogen content.
- Intervention effect N30 versus N0 significantly raised protease activity at pH 4.
- Intervention effect At pH 7 soil nitrogen lowered enzyme activity nonsignificantly.
- Observation Two thirds of grain nitrogen was translocated by day 28.
- Observation Three leaf blades contributed 22.7% of grain nitrogen at N0.
- Observation Three leaf blades contributed 32.6% of grain nitrogen at N30.
- Observation Three leaf blades contributed 48.5% of grain nitrogen at N120.
- Observation Most applied soil nitrogen was reduced by the three leaf blades.
