Since salinity is one of the destructive stresses on moringa growth, applying proper method can be efective to diminish its harmful impacts. This research was done in 2022-2023 in Kushk Hazar in Beyza city of Fars province.This factorial research was done as a completely random design to investigate the impact of copper nanoparticles (0, 5, 10 and 20 ppm) on the morphological and elements content of moringa under sodium chloride salinity (0, 3.9, 7.8 and 11.7 dSm-1). The results indicated the significant effect of salt and nano copper levels on the assessed traits. Salinity made decreases in shoot dry weight, chlorophyll content (total, a and b), calcium and increases in ion leakage, carbohydrate, chlorine, sodium and potassium. The lowest shoot diameter and leaf number observed in plants received 11.7 dS m-1 salinity. Under 7.11 dSm-1 salinity, nano copper spraying improved shoot fresh weight (22%), carbohydrate (45%) and potassium (22%) and lessened chlorine, sodium and calcium content (16, 29 and 42% respectively). In general, it can be concluded that foliar spraying of copper nanoparticles (up to 20 ppm) can play an effective role in reducing the adverse effects of salinity in moringa plant and increasing plant growth and yield.
