    used were Green Gold, Larissa, Mikado, Ohio and Matador. In addition to four NaCl levels of 50, 100, 150 and 200 mM, the treatments were repeated with 10 mM K and 10 mM Ca at each NaCl level. The results revealed that Na+ and Cl- concentrations were significantly increased and the K+, Ca2+ and NO3- concentrations were decreased with increasing NaCl concentrations in the growthgrowthSubject Category: Natural Processes

    , increased the K+, Ca2+ and NO3- concentrations, resulting in an improvement in the marketable yield of the spinach plants. Even though the effects of supplemental K+ and Ca2+ were similar in some plants at different salt concentrations, the effect of additional Ca2+ alone was higher overall. Thus, the results of this study confirmed the principal effects of K+ and Ca2+ supplies in reducing the detrimental effects of salinity.
