Growth and cations accumulation in moringa plants cultivated in saline soils Crescimento e acúmulo de cátions em plantas de moringa mantidas em solos salinos
<p>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...
