Salinity tolerance thresholds of field crops:

• Barley (Hordeum vulgare) is globally recognized as the most salt-tolerant cereal crop, capable of tolerating electrical conductivity ($EC_e$) levels up to $8.0\text{ dS/m}$ before yield decline begins, and producing acceptable yields even at $12-16\text{ dS/m}$.
• In contrast, green gram is highly sensitive ($EC_e \lt 1.5\text{ dS/m}$), while maize and rice are moderately sensitive.
