  To evaluate the residual effects of sodium carbonate of irrigation water on barley (Hordeum vulgare) and chemical markers activity, an experiment was carried out in research field of Karaj Islamic Azad University in 2013 with split plot based on Completely randomize blocks design with four replications. In this experiment barely cultivars including Valfajr and Aras were in main plot and different rates of sodium carbonate of irrigation water in four levels (control,1, 2 and 3 meq lit–1) were in sub plot. In this experiment the traits such as grain yield, 1000 seed weight and the rate of chemical markers such as malon dialdehyde, di tyrosine and di hydroxy guanosine were assayed. The results showed that there was significant difference between sodium carbonate of irrigation water and cultivar treatments at 1% level also mean comparison represent decreased about 41.3% of grain yield with affected by high rates of sodium carbonate in comparison with control. The results also revealed that the level activity of chemical markers was highly affected by sodium carbonate of irrigation water and caused increasing them. In general, Valfajr identified as more resistant cultivar to sodium of irrigation water. Moreover, the rate of chemical markers can be used in selected resistant cultivars to salinity of irrigation water. Manuscript profile
