Effect of Calcium Chloride on Growth and Yield of Tomato Under Sodium Chloride Stress

The effects of salinity and supplied calcium chloride on growth andleaf ions concentration of tomato (lycopersicon esculentum l.) were investigatedin gorgan, iran. a factorial experiment was conducted based on rcbd withfour nacl levels (0, 50, 100, and 150 mm) and four cacl2 levels (0, 100, 200and 300 mg l-1). data of growth, yield and leaf's ca, k, and na content weresubjected to analyze of variance. the results showed that fruit yield decreasedunder salinity stress. increasing ca2+ concentration in the nutrient solutionincreased the fruit yield. leaf ca2+, k+, and n content decreased under salinitystress. tomato in its response to nutrient solution, salinized with sodiumchloride and calcium chloride. the results obtained from this experiment showthat salinity stress caused a significant reduction in plant growth, leaf numberand fruit weight.
