    Salinity is the process by which water soluble salts accumulate in soil. Plants growth can be directly affected by salinity. The overall salinity is one of the main factors that limit the spread of plants in their natural habitat. This study aimed to investigate the effect of salinity and growth and germination of Faba bean. Greenhouse experiment was conducted to assess the effects of soil salinity on germination, seedling emergence, leaf number, stem height, root elongation and biomass of common bean plant. Sodium chloride (NaCl) was dissolved in tap water to saline the soil to 2, 4, 6, and 8dSm-1 electro-conductivity. High level salinity of 6 dSm-1 and 8 dSm-1 caused a significant reduction in stem height, leaf number and biomass and delayed seedling emergence. It also significantly (P<0.05) decreased seed germination. The tap-root length significantly increased as soil salinity increased. An increase in elongation of tap root at high soil salinity indicates an adaption of common bean to saline stress. In general high level salinity i.e 6dSm-1 and above is very sensitive to Faba bean (Vicia faba L.), and it affects the whole growth of plants.
