- Intervention effect Drought significantly reduced sweet potato leaf and petiole biomass.
- Intervention effect Drought slightly increased sweet potato root biomass.
- Intervention effect Drought markedly increased sweet potato leaf water use efficiency.
- Intervention effect Higher potassium fertilization reduced leaf, petiole and total biomass.
- Intervention effect K150 produced greater water use efficiency than no potassium or K300.
- Intervention effect Drought significantly reduced net photosynthesis, transpiration and stomatal conductance.
- Intervention effect Drought significantly reduced intercellular carbon dioxide concentration.
- Intervention effect Drought significantly increased stomatal limitation and water use efficiency.
- Intervention effect K150 to K300 fertilization increased stomatal conductance, transpiration and intercellular CO2.
- Intervention effect K150 to K300 fertilization decreased stomatal limitation and water use efficiency.
- Intervention effect K150 did not obviously change Rubisco activity or chlorophyll contents.
- Intervention effect K300 significantly decreased Rubisco activity and chlorophyll contents.
- Intervention effect Potassium application increased water productivity.
