Symbiosis with VAM under salt stress can affect on yield and growth parameters. In order to evaluate the effect of salinity (NaCl) and symbiosis of VAM on growth parameters and yield of sorghum (c.v.speed feed). The factorial experiment conducted based on complete block design with three replication and two levels of VAM. (Control (M0) and VAM (M1)) and three levels of salinity (0/8, 7, 14dS/m NaCl). Sorghum seedlings inoculation with Glomus intradices. Until emergence irrigated with (0/8dS/m) water and then treatment with saline water. Result showed that above ground length ,leaf area, dry weight stem and root, and shoot/root dry weight were significant (P<0.01), (P<0.05). Glycine betain (GB) content of leaf under different salinity and VAM levels was not significant but GB in root under salinity levels was significant (p<0.01) and VAM symbiosis and VAM*salinity interaction was not significant. VAM had not impact on GB content
