e0“Drought, equivalent to soil water potential of -0.64 MPa, decreased the leaf water potential to -1.67, -1.83, -0.34 and -1.32 MPa and resulted in dry matter yield reduction of 36.4%, 23.9%, 17.6% and 14.5% in faba bean, pea, common bean, and chickpea, respectively”

- Intervention effect Drought reduced faba bean dry matter yield by 36.4%.
- Intervention effect Drought reduced common bean dry matter yield by 17.6%.
- Intervention effect Drought reduced chickpea dry matter yield by 14.5%.
- Intervention effect Drought decreased faba bean leaf water potential to -1.67 MPa.
- Intervention effect Drought decreased pea leaf water potential to -1.83 MPa.
- Intervention effect Drought decreased common bean leaf water potential to -0.34 MPa.
- Intervention effect Drought decreased chickpea leaf water potential to -1.32 MPa.
- Mechanism Turgor maintenance augmented chickpea and common bean yield under drought.
- Observation Common bean had the highest turgor, 1.0 MPa, despite the lowest solute accumulation.
- Mechanism In most legumes, increased solute pool reflected concentration from water loss and growth inhibition.
- Observation Chickpea sugars and sugar alcohols contributed more than 50% of the osmotic pool.
- Observation Chickpea amino compounds contributed 20% of the osmotic pool.
- Observation Calcium contributed 19% of the osmotic pool.
- Observation Potassium did not contribute to osmotic adjustment under drought.
- Recommendation The authors recommend distinguishing concentration effects from active osmotica before selecting for drought resistance.
