e0“Average yield of maize (Zea mays L.) in Mozambique is low”
e1“examined the impact of three tillage methods (hand hoeing, strip tillage and conventional tillage), two fertiliser levels (0 and 40% N) and two water supply regimes (rainfed and irrigated)”
e5“Irrigation had the largest impact on root and shoot growth and crop yield”

- Intervention effect Tillage had a major effect on soil penetration resistance.
- Intervention effect Tillage had little effect on maize root growth.
- Intervention effect Tillage had limited effect on maize grain yield.
- Observation There was no interaction between tillage and the other experimental factors.
- Recommendation There appears to be little need for loosening this sandy soil for maize.
- Intervention effect Irrigation increased maize yield in season 2 from 670 to 4780 kg ha–1 compared with rainfed maize.
- Intervention effect Fertiliser gave no yield increase in the rainfed treatment.
- Intervention effect Fertiliser combined with irrigation increased maize yield by 1590 kg ha–1 in season 1.
- Intervention effect Fertiliser combined with irrigation increased maize yield by 1840 kg ha–1 in season 2.
- Observation There was a very strong interaction between fertiliser and water supply.
- Recommendation For the conditions studied, fertiliser should be added only in combination with irrigation.
