Abstract: The experiments for present research work were conducted in the botanical garden of Department of Biological Sciences, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad from a period during October, 2013 to February, 2014. The pot experiment was planned in complete randomized design with three replications for each treatment. Salinity stress hinders plant growth and cause significant yield losses and therefore, induction of salinity stress tolerance in crop plants is one of major goals of agriculture research. Tomato is a crop plant with high nutritive value and its cultivation is dependent on many environmental factors, viz. temperature, salinity, nutrients etc, which can affect the yield and reproductive potential of the plant. On the basis of some growth parameters and finally the yield, 20 tomato varieties were selected as salt efficient tomato varieties. Twenty tomato varieties were taken to record several growth and biochemical parameters under the treatments- 1) Control, 2) 25μM SA, 3) NaCl 50 mM, 4) NaCl 100 mM, 5) NaCl 150 mM, 6) NaCl 200mM, 7) NaCl 50 mM + 25μM SA, 8) NaCl 100 mM + 25μM SA, 9) NaCl 150 mM + 25μM SA and 10) NaCl 200 mM + 25μM SA. The interactive effects of salicylic acid (SA) as shoot spraying on NaCl stressed tomato plants grown in experimental pots under different salinity levels (0, 50, 100, 150 and 200 mM NaCl, respectively) were studied. An increase in the degree of salt tolerance induced by salicylic acid was indicated by finally the yield. The data provided evidence that salicylic acid treatment reduced the adverse effects of salt stress on tomato plants and might play a key role in providing stress tolerance by stimulation of the antioxidant system as a stress protection mechanism.
