Abstract

The purpose of this study was to investigate the effect of SALT STRESS on growth, biological nitrogen fixation (BNF), and salinity tolerance of three soybean cultivars (Jk, Sahar, and Gorgan3). These cultivars were planted in a factorial experiment, completely randomized, with four replicates and two variables that included the aforementioned cultivars and four salinity levels (1, 4.2, 5, and 5.8 dS/m). The plants were grown in 48 pots and were harvested after 1 month and their nodule number, fresh and dry weight of root and shoot, biomass, nitrogen percentage, and nitrogen content were measured. Results showed that with increasing salinity, all traits decreased.Means comparison showed that cultivar Jk was better than the other cultivars with respect to nodule number, fresh weight and dry weight of root and shoot, biomass, nitrogen percentage, and nitrogen content. Accordingly, cultivar Jk had the lowest sensitivity to salinity and could be considered a promising genotype for BREEDING PROGRAMS.
