Aim and Background: In order to evaluation of seed priming on Moderating of salinity effect on germination and primary growth of cucumber in pot planting, an experiment carried out by Factorial design with RCD at three replication in greenhouse of Zahedan Jihad Keshavarzi in 2012. Material and methods: The main factor was salinity at three level consider EC=2, EC=4 and EC=6 mmohs/cm and second factor was seed priming in four level consider control, KNO3, KCl and NaCl. Results: The variance analysis of data showed that salinity had meaning effect on the all of investigated traits. The most germination percentage with 97.58% obtained in control treatment. The maximum biomass as well as in this treatment with 55.26 gram. The seed priming had meaning effect on the all traits except leave number, stem diameter and the time need for emergence. The most germination with 88.11% obtained in KNO3 treatment this treatment as well as with 43.92 gram had the most biomass. The correlation effect of salinity × priming had no significant effect. Conclusion According to this results cucumber cultivation not recommended for Areas where the irrigation water is saline.
