- Intervention effect Salinity increased hydrogen peroxide concentration in barley.
- Intervention effect Salinity reduced barley grain yield.
- Observation Barley peroxidase activity increased by 22% in year one and 33% in year two under salt stress.
- Observation Barley catalase activity increased by 28% in year one and 20% in year two under salt stress.
- Observation Barley superoxide dismutase activity increased by 57% in year one and 45% in year two under salt stress.

- Intervention effect Foliar salicylic acid above 0.5 mM enhanced four antioxidant enzyme activities.
- Intervention effect Foliar salicylic acid above 0.5 mM enhanced yield.
- Intervention effect Higher salicylic acid concentrations reduced grain yield in salt-stressed barley in both years.
- Mechanism Authors attribute yield reduction under high salicylic acid to an adverse interaction with antioxidant enzymes.
- Mechanism Authors conclude salicylic acid mitigated salt stress through enhanced antioxidant activity and improved yield.
