Abstract Background Salinity is a major abiotic stress, and the use of saline water in agricultural sector will incur greater demand under current future climate changing scenarios. The objective this study was to develop dual-functional nanofertilizer capable releasing micronutrient that nourishes plant growth while enhancing salt stress resilience faba bean ( Vicia L.). Results Moringa oleifera leaf extract used synthesize sulfur nanoparticles (SNPs), which were applied as foliar spray at different concentrations (0, 25, 50, 100 mg/l) mitigate negative effects (150 mM NaCl) on plants. SNPs characterized found be spherical shape with an average size 10.98 ± 2.91 nm. results showed had detrimental photosynthetic performance (Fv/Fm) compared control, spraying improved these parameters salinity stress. application also increased levels osmolytes (soluble sugars, amino acids, proline, glycine betaine) nonenzymatic antioxidants, reducing oxidative biomarkers (MDA H 2 O ). Moreover, treatment stimulated activity antioxidant enzymes (ascorbate peroxidase (APX), (POD), polyphenol oxidase (PPO)) upregulated expression stress-responsive genes: chlorophyll a-b binding protein LHCII type 1-like (Lhcb1), ribulose bisphosphate carboxylase large chain-like (RbcL), cell wall invertase I (CWINV1), ornithine aminotransferase (OAT), ethylene-responsive transcription factor 1 (ERF1) , greatest upregulation observed 50 mg/l SNPs.
