Abstract

The aim of this work was to evaluate the salinity effects on growth and dry matter and cations accumulation in moringa plants (Moringa oleifera). The experiment was conducted in completely randomized design, with four treatments, consisting of four soils (electrical conductivity (EC) 0.49 (control), 4.15, 6.33, 10.45 dS m-1) with four replications. Initially the plants were grown in rigid tubes, and 30 days after emergence, were transferred to pots containing 10 kg of soil, according to the salinity treatment. The parameters evaluated were plants height and dry matter and N, K, Ca, Mg and Na accumulation in shoots and roots. The salinity is detrimental to initial plant growth and cation accumulation in shoots and roots plants. Young moringa plants were not effective in inhibiting the absorption of Na and its translocation to the shoot.
