Soil salinity is one of the world's most important problems. Many studies have tried to find a solution to this problem. Therefore, this report aimed to determine the tolerance of salt concentrations for pole bean (Phaseolus vulgaris L.) plant growth naturally. The current experiment examined the effect of irrigation with saline water on seed germination and seedling growth. Seeds were grown in media containing 0.0, 50, 100, 150, and 200 mM NaCl. Therefore, the number of germinated seeds decreased according to the media concentration. 15-day-old pole bean seedlings were irrigated with saline water at different concentrations (0.0, 50, 100, 150, and 200 mM NaCl). Later, seedlings are watered with tap water for 15 days. After that, the soil and plant shoot samples were collected for analysis purposes. Our results showed that soil pH, EC, and moisture enhanced as salinity levels increased. The responses of pole bean plants to salt stress were documented. Pole bean shoots have gradually increased both soluble carbohydrates and protein content, with the increase of salt levels and free amino acids compared to control. However, photosynthetic pigments and carotenoids of the pole bean leaves were higher in control than under salt concentrations.
