A field trial was conducted at NIA experimental farm, Tandojam, Pakistanto study the effect of different Rhizobial strains on the survival and growthof two Australian Acacias viz., Acacia ampliceps and Acacia stenophylla undersaline condition. Inoculation of tree seedlings improved survival and growth ofboth Acacia species as compared to uninoculated ones. A. stenophylla showedhigher survival as compared to A. ampliceps, whereas the over all performanceof A. ampliceps was much better. A. ampliceps inoculated with rhizobial strainno. 63/1 showed greater plant height, stem diameter and plant canopy followedby 403/1 and 399/1. Performance of tree seedlings with the application of 100mg N/kg of soil alone was better as compared to two strains of Rhizobia. A.stenophylla, inoculated with strain no. 403/1 proved better for its symbioticpartner followed by 63/ l. The uptake of nitrogen by plant also increased ininoculated plants but the values for N-content in seedlings without Napplication were higher.
