Salinity stress hampers plant growth and crop productivity. The growth and yield of coriander are severely affected by soil salinity. A pot experiment was performed to investigate the effectiveness of zinc and iron foliar application along with spray adjuvants under salinity stress. The single foliar application of micronutrients was carried out under normal and saline conditions (7 dS m-1) at the vegetative growth stage (21 days after germination). The results showed an increase in plant biomass, relative water content, antioxidant activities, and zinc and iron concentrations in coriander. The shoot dry biomass was significantly improved by 107 and 203%, respectively, in both control and saline conditions where zinc + iron + adjuvant was applied. The same treatment combination reduced the membrane damage, increased antioxidant enzyme activity, and improved gas exchange attributes (27% increase in photosynthesis rate compared to the control) and mineral contents in coriander plants under saline conditions. The application of zinc and iron was beneficial in mitigating salinity stress in coriander plants, and their effectiveness was increased by the addition of spray adjuvants.
