- Intervention effect Ridge tillage significantly suppressed maize seedling emergence during infrequent rain and long dry spells.
- Intervention effect The ridged seedbed reached soil temperatures over 40°C at 5 cm, about 10°C warmer than no-till mulch.
- Observation Soil oxygen diffusion rate was greatest under no-till mulch.
- Observation Soil oxygen diffusion rate was lowest in furrow bottoms.
- Intervention effect No-till plots retained more soil moisture than ploughed treatments.
- Intervention effect Ridges adversely affected maize plant height and vigour during frequent dry spells.
- Association Maize grain yield declined as mechanical tillage intensity increased during dry-spell seasons.
- Intervention effect Cumulative no-till grain yield exceeded ploughed treatments by 0.32 tonnes ha −1.
- Observation Mean seasonal maize yield was 3.37 t ha −1 in first seasons.
- Observation Mean seasonal maize yield was 1.00 t ha −1 in second seasons.
- Association Seasonal maize grain-yield fluctuation was related to rainfall amount and growing-season length.
