The effectiveness of exogenous application of calcium in ameliorating the adverse effects of salt stress (15.9 dS m^-1) on date palm offshoots (Phoenix dactylifera L. cultivars of Berhi and Sayer) was investigated. Ca-fertilisers Polixal and Rexene were applied either as soil amendments or foliar spray. The results showed that Polixal at 30 ml offshoot^-1 significantly increased plant height, leaf area, total chlorophyll content, RWC, proline concentration, peroxidase activity, IAA content, K⁺ and K⁺/Na⁺ ratio in leaves of Berhi cultivar, whereas catalase activity, ABA and Cl^-  content were decreased. Also Berhi cultivar responded to soil amendments more than to foliar spray. However, Ca-fertilisers mitigated salt stress in the two cultivars and Berhi cultivar was more salt stress tolerant than Sayer cultivar by maintaining the high ratio of K⁺/Na⁺ and regulating levels of IAA to ABA, in silty clay loam soil. These results suggest that calcium application can improve the defense system under salt stress conditions.
