The effect of GA3 on growth of chickpea var. RSG-888 under different levels of salinity was studied. A gradual reduction in shoot length, leaf number, fresh weight and dry weight was observed under salt stress. GA3 treatment increased the shoot height, leaf number under salt stress. It also improved fresh and dry weights of plant. Significant results were obtained for all the growth parameters observed under salt stress. Plant height and fresh and dry weight of shoot decreased under salinity stress. Application of 2.5 and 5 ppm gibberellic acid compensated this adverse effect of salinity. The efficiency of gibberellic acid is to mitigate the effect of salinity reduced with rise in salinity.
