The inadequacy of sewage systems and water shortages in semi-arid Northeast is encouraging the reuse of water in the production of agricultural crops. This study aimed to analyze the effect of treated do- mestic sewage in the initial development of three melon cultivars in Mossoró-RN. The experiment was mounted on a split-plot in randomized blocks with plots cultivars of melon (Yellow Tikal, Cantaloupe type Harper and Gália) and the split-plots the proportions of water supply and domestic sewage (T1 - 100% water supply T2 - 50% of water supply and 50% of domestic sewage, T3 - 25% of water supply and 75% of domestic sewage and T4 - 100% domestic sewage) in three replicates. In the experimental period were analyzed for physico-chemical and microbiological characteristics of sewage and water supply. At 20 days after sowing was measured plant height, stem length, root length and stem diameter. The results showed that the fertirrigation of melon cultivars with domestic sewage minimizes the effect of water scarcity in semiarid. The development of cultivar Gália seedlings was not affected by application of primary domestic sewage. The T2 and T4 were the most suitable for the production of cultivar Gália seedlings.
