The aim of this work is to evaluate the chemical attributes of substrate, emergence, survival and quality of Anadenanthera peregrina var. falcata (Benth.) Altschul (angico-do-cerrado) seedlings in different substrates and with or without biostimulator of soil microbiota. We evaluated three types of substrates – ‘Cerrado’ soil (restricted sense), commercial Tropstrato® substrate and native forest soil (‘Cerradão’) – with or without biostimulator application, arranged in a 3 x 2 factorial scheme, in randomized blocks, with four repetitions. Seedling emergence was low (38.05%), but the highest survival occurred with application of biostimulator (81.01%) and commercial substrate (87.61%). The highest height (8.60 cm), number of leaves (13.00/plant), stem diameter (1.86 mm) and leaf area (43.44 cm2/plant) of seedlings as well as highest dry masses, occurred in the native forest soil, the dry masses were also favored with the application of biostimulator. Results indicated that native forest substrate and biostimulator application provides greater growth and quality of ‘angico-docerrado’ seedlings.
