This experiment was carried out to study the effect of soil mulch and the application of some treatments (control, urea, complete fertilizer and polyaxal) and their interaction in alleviation of salt stress on Cauliflower which cultivated in salty soil(11.3 dS/m-1 ) under drip irrigation , by estimating of leaf area, SOD and Catalase activity , MDA and Glutathione concentration in both of leaves and flowers. Soil mulch showed a significant increase in leaf area, SOD and Catalase activity ,Glutathione concentration and a significant decrease in MDA concentration in both of leaves and flowers compared to no mulch treatment . Complete fertilizer treatment caused higher significant effect compared to control treatment . The interaction between complete fertilizer and mulch was superior in leaf area (288.3cm2 ) compared to control (73.5 cm2 ) and gave increases in SOD and Catalase activity in addition of Glutathione concentration compared to control treatment in both leaves and flowers , while it caused significant decrease in MDA concentration in both of leaves and flowers.
