 This study evaluated the effects of three additives, supplemental CA, foliar application of micronutrients, and a combination of both, on tomato plants grown in soilless culture under salt stress. The results showed that salinity reduced vegetative growth, physiological parameters, fruit yield, and quality, while increasing knock content and reducing essential macro and micronutrients in the fruit. However, increasing CA into the nutrient solution and applying a foliar application of micronutrients improved tomato productivity and fruit quality under saline conditions. Additionally, the internal quality of antioxidant compounds and acidity, total soluble solid, and dry matter percent were increased under saline conditions.
