Soil salinity is a major abiotic stress influencing plant productivity worldwide. Acacia nilotica and Prosopis cineraria are one of the most important multipurpose tree species in the arid and salt prone areas of Rajasthan. A field experiment conducted during summer season of 2003 and 2004 to study the seedling growth behaviour of A. nilotica and P. cineraria on the saline soil of different treatment levels. The aim was to test the hypothesis that A.nilotica and P cineraria being a halophytic species showed different salt tolerance responses. Application of medium salt level 4d Sm-1 resulted in the maximum growth of the species. A. nilotica had the highest biomass, response breadth over the P. cineraria. Thus rehabilitation of arid soils with the above recommended tree species using the available saline waters , would not only render these abandoned soils to be productive but would also ensure conservation and improvement for long range ecological security on these lands. Our results revealed that salt tolerant species could be conveniently screened by a salt tolerance index at the threshold salinity over its preceding salinity level.
