Abstract
Algae differ in their adaptability to salinity and on the bases of their tolerance extent they are grouped as halophilic (Salt requiring for Optimum growth) and halotolerant (having response mechanism that permits their existence in Saline medium) (Rao,et al,2007) in their case algae produce some metabolites to protect themselves from salt injury and to balances the surroundings Osmotica (Richmond,1986)
Excessive Soil Salinity usually results from natural processes or from irrigation With Saline Water.
Salinization is a major cause of soil degradation and affects 19.5%of irrigation With Saline Water .
