- Intervention effect Elephant grass was the most effective fallow cover, followed by Guinea grass and pigeon pea.
- Intervention effect Fallow increased maize yields at two southerly stations.
- Intervention effect Fallow did not increase maize yields at three more northerly stations.
- Intervention effect Andropogon grass fallow was less successful on northern nitrogen-deficient soils than elephant or Guinea grass on southern rich soils.
