Key Points

To evaluate the effects of foliar-applied chitosan nanoparticles on mineral uptake, physiological performance, and biochemical responses in maize exposed to salinity stress.
Subjected maize plants to salinity stress using sodium chloride at concentrations of 0, 50, and 100 mM.
Applied chitosan nanoparticles as exogenous foliar sprays at concentrations of 50 and 100 mg L⁻¹.
Salinity stress markedly diminished mineral content, water availability, photosynthetic pigments, and photosynthetic efficiency while elevating stomatal disruption, ion leakage, and hydrogen peroxide accumulation.
Foliar chitosan nanoparticle treatments alleviated salt-induced damage by stimulating antioxidant defenses, lowering oxidative stress, and preserving redox homeostasis and photosynthetic performance.
