The objective of this work was to evaluate the effect of the inoculation of the arbuscular mycorrhizal fungus (AMF) Claroideoglomus etunicatum on the development of Salicornia neei subjected to five treatments: water, desalinator reject, reject plus one dose (7 g) of NaCl, reject plus two doses of NaCl and reject plus three doses of NaCl. The experiment was conducted under greenhouse conditions at the Agronomic Institute of Pernambuco – IPA, in a completely randomized design, with autoclaved and non-autoclaved soil, with three replications. A dose corresponding to 1.0 mL ̸ kg of Hoagland & Arnon complete nutrient solution soil was added to each well and watered daily with the corresponding treatments. In the conduction of the experiment, polyethylene vessels with 8 kg of saline soil were used. The results showed that the reject with the intermediate doses (Reject + 1NaCl and Reject + 2NaCl) was more significant for the growth (17.16 cm and 17.37 cm respectively) of Salicornia neei.
