The use of reuse water, despite the undesirable characteristics due to salinity of the water, is a practice increasingly used for the production of forage in the semiarid. Its indiscriminate use can compromise the production of fodder as well as cause great damage to the environment. It is necessary to develop techniques that provide a significant production of fodder, but also to minimize the salinization of the soils with the reuse of these waters. For this reason, the objective was to evaluate the performance of sorghum plants irrigated with saline tail, following the transpiration and the stomatal conductance at different stages of growth, as well as their production. The experiment was carried out at the Serra Talhada Academic Unit, in a 3x2 + 1 factorial scheme with 3 replications, where factor 1 was the time of beginning of irrigation with waste water (15, 30 and 45 days after emergence), Factor 2 was the concentrations of the reject (50 and 100% of the salt reject). The present work showed that for the sorghum growth, the beginning of irrigation at 45 days after emergence and the dilution of 50% of reject presented better results. For the dry matter accumulation all treatments were inferior to the control, while the natural matter of the aerial part with the beginning of the irrigation at 45 days independent of the reject and at the 30 days with 50% of the reject were similar to the control. For transpiration treatments with 100% saline reject with irrigation start at 30 and 45 days after emergence and treatment with 50% of the reject initiated at 45 days after emergence did not differ from control, and for conductance only treatment with 50% of the reject started at 45 days after emergence did not differ from the control. Therefore, it is advisable to start irrigation with reject water at 50% reject concentration and 50% potable water at 45 days after emergence.
