Salt stress severely limits global crop productivity by disrupting ionic balance, physiological processes, and cellular ultrastructure, particularly in salt-sensitive forages like alfalfa (Medicago sativa L). Addressing this issue requires environmentally feasible innovative strategies. This study investigated the comparative potential of Nano-FeO FeSO4 (30 mg kg-1) soil supplements with rhizobium on salt tolerance employing morphological, physicochemical, approaches. The results demonstrated that FITC-nFeO significantly reduced Na+ uptake, enhanced K+ accumulation, improved Na+/K+ ratio roots shoots relative to FeSO4. Scanning electron microscopy illustrated ameliorated root ultracellular structure leaf stomatal functionality, facilitating gaseous exchange characteristics photosynthetic performance. Confocal laser scanning confirmed FITC-tagged nFeO adhesion roots, supported transmission findings preserved chloroplast ultrastructure under application. also mitigated oxidative damage ROS, as evidenced hydrogen peroxide, electrolyte leakage, thiobarbituric acid reactive substances (TBARS) content, through antioxidant enzyme activities. Overall, comparison FeSO4, retrieved salt-induced damages promoting morpho-physiological integrity. highlights role nanotechnology enhancing resilience salt-contaminated soils, paving way for eco-friendly remediation

Resumen: El nitrógeno gas o dinitrógeno (N2) constituye aproximadamente el 78% del aire, pero no puede ser utilizado por la mayoría de los organismos. Solamente las formas oxidadas como nitrato (NO3-) reducidas amonio (NH4+) son asimilables plantas. Un gran número leguminosas capaces establecer simbiosis con bacterias fijadoras presentes en suelo, conocidas genéricamente rizobios, lo que les permite reducir N2 a nódulos. La fijación biológica una alternativa al uso fertilizantes industriales, cuya producción es un proceso costoso y conlleva múltiples problemas medioambientales, emisión gases causan efecto invernadero contaminación suelos agua.
