- Intervention effect Aerobic conditions raised root hydrogen peroxide concentration by 24.6%.
- Intervention effect Aerobic conditions raised root proline concentration by 20%.
- Intervention effect Aerobic conditions lowered root soluble protein concentration by 20%.
- Intervention effect Aerobic conditions reduced yield by 17% versus semi-aerobic conditions.

- Observation ‘Apo’ yielded 4.0 t ha −1 under aerobic conditions.
- Observation ‘IR 74371‐3‐1‐1’ yielded 3.80 t ha −1 under aerobic conditions.
- Recommendation The authors suggest supplementary irrigation at critical stages under semi-aerobic conditions to alleviate yield decline.
