- Observation Soil water content declined as depth increased.
- Observation Topsoil water content varied more than subsoil water content.
- Intervention effect At the same N level, P raised soil water content above 50 cm.
- Intervention effect At the same N level, P lowered soil water content below 50 cm.
- Observation Soil water storage fluctuated up, down and up over four stages.
- Intervention effect N plus P gave more soil water storage than N alone at seedling stage.
- Observation Storage peaked with P at 120 kg/hm2 in other stages.

- Intervention effect N plus P lowered storage below 50 cm relative to N alone.
- Intervention effect N plus P sharply improved grain yield.
- Observation Grain yield peaked at 120 kg/hm2 P and declined above that rate.
- Observation Water use efficiency peaked at 120 kg/hm2 P and declined above that rate.
