This study aimed to evaluate the establishment of Anadenanthera colubrina (Vell.) Brenan var. cebil [Griseb.] Altschul inoculated with mycorrhizal fungi and fertilized in the Pantanal of Nhecolândia, Mato Grosso do Sul State, Brazil. The experiment was established in March 2015 in a deforested “cordilheira” environment, in randomized blocks distributed in micro-relief, with subdivided plots. The main treatments corresponded to seedlings submitted or not (control) to Rhizophagus clarus and Gigaspora margarita mixed inoculation. The secondary treatments were doses of ammonium sulfate and potassium chloride fertilizers. We monitored from 2015 to 2017 the plants the plants under shading from the presence of remnant tree after deforestation, as well as the percentage of survival and growth parameters of A. colubrina. The best survival condition occurred in the portion of relief adjacent to the freshwater lake, under moderate shading, with the application at planting of 15 g of ammonium sulfate and 5 g of potassium chloride per plant. Mycorrhizal inoculation promoted 16% increase in diameter at 23 months of age, not increasing the species survival. We recommend complementary studies to support management strategies of A. colubrina under planting conditions in the Brazilian Pantanal.
