Abstract
Dark septate endophytic fungi (DSE) associate with plants can facilitate their initial growth by solubilizing phosphate and acquiring water and nutrients from the soil. The aim of this study was to evaluate the effect of inoculation of DSE (Curvularia lunata) on maize seedlings, in response to rates of phosphorus (P) applied to the soil, by analyzing the P levels in plants and soil, as well as nutrients in the plants, and root colonization of DSE and autochthonous arbuscular mycorrhizal fungi (AMF). The experiment was developed in a greenhouse at the Faculty of Engineering (UNESP-FE, Ilha Solteira Campus, São Paulo State, Brazil). The experimental design was entirely randomized in a 4 × 2 factorial scheme: 0, 25, 50 and 100% of triple superphosphate (45% P2O5), the mineral crop recommendation (90 kg ha−1), and DSE inoculation (with and without), with four repetitions and one plant per pot. The following parameters were evaluated: available P content in the soil and P, potassium (K); calcium (Ca); magnesium (Mg); sulfur S; copper Cu; iron (Fe); manganese (Mn) and zinc (Zn) contents in the roots and the shoot; fresh shoot and root biomass, and root colonization by DSE and AMF, at 30 days after plant emergence. The DSE inoculation combined with P2O5 rates increased the amount of P available in the soil. P, K, S, Fe and Zn contents in roots, especially at the 0% P rate, were increased by inoculation with DSE. The inoculation increased root colonization by DSE and decreased root colonization by AMF.
