Leaf contents (%) of nitrogen (N), phosphorus (P), potassium (K) of Senegalia polyphylla in non-competitive cultivation 120 days after transplanting in a substrate containing dystrophic red latosol. The solid line (-) represents leaf content values in mineral (MF) and organic (OF) fertilizations, the dotted (...) the control (0–0%), and the dashed (--) the upper and lower limits of sufficiency ranges. The upper and lower axes, per graph, show the combinations of MF and OF. * significant at 5% via the F test.
