Other claims from this paper (9)
- Intervention effect Drought reduced sorghum growth and photosynthesis.
- Intervention effect Drought raised mean HCN content by 27.85% over well-watered plants.
- Intervention effect Drought increased proline and soluble protein content in leaves of all three genotypes.
- Intervention effect Drought increased leaf O 2 −, H 2 O 2 and MDA content in all three genotypes.
- Intervention effect Drought increased leaf antioxidant enzyme activities in all three genotypes.
- Intervention effect The 120 kg N ha −1 rate produced maximum plant growth.
- Intervention effect The 120 kg N ha −1 rate increased plant nitrogen and phosphorus content compared with lower rates.
- Intervention effect Increasing nitrogen from 90 to 120 kg N ha −1 sharply raised HCN content.
- Recommendation The authors suggest 90 kg N ha −1 under drought to balance defense and food safety.
