- Observation D24 grew better than P1921 under rain-fed unamended conditions.
- Intervention effect Biochar increased D24 root area by 38% at silking.
- Intervention effect Biochar reduced the fraction of finer roots in D24.
- Intervention effect Biochar increased the fraction of finer roots in P1921.
- Intervention effect D24 maintained maximum transpiration at a lower soil water fraction, from 82% to 45%.
- Intervention effect P1921 maintained maximum transpiration at a lower soil water fraction, from 46% to 22%.
- Intervention effect Plant nutrient contents did not vary significantly under biochar.
- Intervention effect Productivity did not vary significantly under biochar.
- Intervention effect Grain protein and starch contents did not vary significantly under biochar.
- Intervention effect Biochar reduced grain lipid content in P1921 by 13%.
- Recommendation Authors conclude biochar can enhance maize drought tolerance, especially in tolerant hybrids.
