Abstract. Salinity is a major problem in reducing most of agronomic crop production in the world. Chloride and Sulfate toxicities in waters and soils are the main factor in reducing growth and yield of most of plants. Tolerance and sensitive indices related to CL and SO4 in irrigation water and effect of municipal refuse compost on barley yield was evaluated in a Completely Randomized Design (Factorial) with three replications, under greenhouse condition. Quantity tolerance and susceptibility indices such as Mean Productivity (MP), Tolerance Index (TOL), Geometric Mean Productivity (GMP), Stress Susceptibility Index (SSI), Reduction Yield Ratio (Yr) and Stress Tolerance Index on the bases of plant yield with (Ys) and without stress (Yp) conditions were determined. Results showed that STI, MP and GMP had positive and high significant correlations with grain and plant biomass yields among other indices. Also CL/SO4 anion ratios 2:1 and 3:1 in grain yield and 3:1 , 2:1 and 1:2 in plant biomass yield imposed highest tolerant in salinity compared to non tolerant stress conditions.
