Soil and water salinity have been increasingly threats for arid and semi-arid regions such as Iran. Salt stress، as one of the most important factors reducing agricultural production، has been subject of numerous worldwide researches for more than 100 years. Review of literature in Iran revealed that filed crops production improvement and breeding research in saline conditions have been widely conducted at Universities and Research Institutes during the last half century. In this study، published Iranian salinity researches from 1977 until present time were investigated and analyzed، and the challenges were discussed and finally some approaches have been suggestd for the future. It seems that lack of well defined strategic plan، shortage of research resources، lack of team-work and poor knowledge of salinity concepts are among the most challenges in salinity research in Iran. Research planning in the field instead of growth chambers and greenhouse experiments، selecting suitable crops for salt affected conditions based on its relative salt tolerance and water use efficiency، and research on emergence and establishment growth stages of crops as a sensitive phase could be some of the applied approaches for improvement of field crops yield in salt affetced conditions. It is hoped that this article can help to the updating of knowledge of researchers and brings new attitudes and visions in salinity research in Iran.
