Abstract: A pot experiment was carried out during winter season 2014 to study the effect of Saccharomyces cerevisiae combined with compost or biogas manure on the chlorophyll content, growth, antioxidant status and mineral uptake of wheat under soil salinity. Two sources of fertilizers for soil amendment: compost and biogas manure were used. Results indicated that, inoculation with Saccharomyces combined with compost or biogas manure in saline soil alleviated the salt stress on the growth parameters, yield, total biomass and enzymatic activity. The inoculation with Saccharomyces cerevisiae also induced a significant stimulatory effect on the chlorophyll pigments and carotinoids. Salinity tolerance measured as percentage chlorophyll stability index (CSI %) was higher under treatment inoculated with Saccharomyces. Data also showed that treatment with Saccharomyces combined with compost or biogas manure succeeded to increase contents of N, P, K of shoot of wheat plant compared to un-inoculated plants. Moreover, inoculation significantly reduced accumulation of Proline (amino acid) content in the shoots and roots, antioxidant enzymes (peroxidase and catalase) of the wheat plants under soil salinity. As a result, treatment with Saccharomyces cerevisiae combined with compost or biogas manure could be alleviating the effect of potentially toxic ions. The un-inoculated plants were more sensitive to salinity than inoculated ones, as indicated by several measured parameters.
