Proper planting crops using saltwater and brackish water can effectively increase the income of farmers and exports out of the country. Most melons are now planted in Khorasan are not suitable for export to other countries. To investigate the possibility of using saltwater and brackishon on Sabzevar late melon (Mahvelati), was experiment with 7 treatments and 3 replications in a randomized complete block design with drip irrigation, in Mashhad. Irrigation treatments were, fresh water from planting to harvest, water (3 dS/m) from planting to harvest, water (6 dS/m) from planting to harvest, water (6 dS/m) from 20 days after plantation to harvest, water (6 dS/m) from 40 days after plantation to harvesting, water (3 dS/m) from 20 days after plantation to harvest and water (6 dS/m) from 40 days after plantation to harvest. Result showed that, wwith increasing salinity, total yield, marketable yield and water use efficiency decreased. But the difference between saltwater and brackish water treatment practices was significant. Irrigation with fresh water at the beginning of the growing season, the product does not increase, but put more stress on the plant. With the increase in salinity and decrease product, still produced fruits are suitable for export.
