Alleviation of green cabbage salt stress by soil mulch and some treatments

In current research, green cabbage plants was exposed to many treatments which was (saline soil (11.3 dSm.m-1), mulch (black polyethylene), and three kindes of fertilizers ( urea , complete fertilizer and PHCA (polyoxal) in addition of control to alleviate salt stress of green cabbage plants in response of( leaf area , (SOD) activity, (CAT) activity ,GSH content and MDA concentration. Mulching soil caused a significant increase in leaf area and, while it caused a significant decrease in CAT activity and MDA content. Complete fertilizer caused the highest increase in leaf area and glutathione concentration than other treatments. GSH content The best treatment in dual interaction was ( mulch+ complete fertilizer) which it caused an increasing in leaf area and GSH content , while it caused a significant decrease in CAT activity.
