Aiming to evaluate the effect of salinity stress on dry matter yield and mineral nutrition of moringa (Moringa oleifera Lam.), Is led by 40 days, an experiment in a greenhouse employing the Hoagland and Arnon (1950), in plastic pots with 3 liter capacity, with one plant each. The experimental design was randomized and the treatments consisted of applying 0; 30; 60; 90; 120 to 150 mol m-3 NaCl with three replications. The solutions were renewed every 10 days with continuous aeration. The jug was highly sensitive to salt stress as the production and loss of leaves, tolerating NaCl concentration equal to or less than 60 mol m-3. The NaCl exerted influence on the accumulation of nutrients in all parts analyzed, being negative in roots and leaves, and positive in deciduous and reduce the efficiency of use of N, P, K, Ca, S, B, considerably , Cu, Fe and Mn in dry matter production.
