Other claims from this paper (6)
- Intervention effect Maize root density increased with P application.
- Intervention effect There was a tendency toward higher root concentration in the upper 10 cm of soil under minimum tillage.
- Intervention effect Movement of broadcast P in the soil profile was slow with minimum tillage.
- Intervention effect Broadcast, band and hill P application were equally effective in supplying adequate P to maize on Egbeda soil at 20 kg P/ha.
- Intervention effect P placement method had no effect on maize yield under either minimum or conventional tillage.
- Mechanism The lower maize yield under minimum tillage in 1974 was attributed to early N stress.
