In this study which was conducted under greenhouse conditions, the impacts of calcium and potassium compounds on the % DM (dry matter) and % EC (electrical conductivity), % RWC (relative water content), and proline, antioxidative system in tomato plant (Lycopersicon esculentum Mill.) under salt stress were investigated. Three different concentrations of salt (50, 100 and 150 mM as NaCl) and potassium and calcium (20 mM as KNO3 and CaNO3) were applied. The compounds of Ca and K which were given in tomato plants in addition to salt, were regulated to antioxidative system, decreased lipid peroxidation increasing with salt and ameliorated RWC%, EC% and DM% by reducing the detrimental effects of salt. Based on these results, it was concluded that Ca and K compounds applied to tomato plant grown under salt stress, supported plant growth and mitigated stress effects.
