Abstract

Aiming to evaluate nutritional requirements and effects of nutrient depravation in developing of seedlings of  barbatimão (Stryphnodendron adstringens (Mart.) Coville), we conducted an experiment in a green house. We employed 12 treatments in a fully randomized block design with eight replications. We applied the following treatments: complete 1 (C1-fertilized with N, P, K, S, B, Cu, Zn and lime as Ca and Mg sources), complete 2 (complete 1 – lime with CaSO4.2H2O and MgSO4.7H2O as Ca and Mg sources), C1-N, C1-P, C1-K, C1-S, C1-B, C1-Zn, C1-lime, C2-Ca, C2-Mg, and control. We measured diameters and heights and separated them into shoot and root system. We dried the samples, weighed them and determined the nutrients levels in shoot dry matter. As result, we identified that phosphorus and boron were the most limiting factor to growth, as well as liming had a negative effect on growth; the sequence of nutritional requirements presented by barbatimão seedlings in relation to complete treatment was: P> B> Zn> Mg> K> N> S> Ca.
