Growth of mangabeira seedlings in different volumes and substrate compositions

Abstract

With an increasing demand for native seedlings, it is essential to carry out studies aimed at defining the substrates and the volumes necessary for the production of seedlings on a large scale. This study aimed to evaluate the production of mangabeira seedlings (Hancornia speciosa Gomes) submitted to different compositions and volumes of substrates. The experiment was carried out in a completely randomized design in a factorial scheme (5 substrates x 3 volumes) with three replications. The following substrates were used: commercial substrate, soil, commercial substrate + soil (1:1 v/v), commercial substrate + soil (1:2 v/v), and commercial substrate + soil (2:1 v/v) and volumes 280, 175 and 100 cm³. The height and diameter of the stem did not differ between the substrates, while the root length was greater in the soil and in the commercial substrate + soil mixture (2:1 v/v). Mangabeira seedlings show greater growth when produced in a commercial substrate + soil mixture (2:1 v/v). The largest volume of tested substrates (280 cm³) provides better growth of mangabeira seedlings.
