Producing Brazilian Cerrado plants, especially ones endangered, is essential for your maintenance. In this way, fertilization is furthermore uncertain. Here, we demonstrate the impact of soil addition of nitrogen (N, 4.20, 18.90, 31.50, 44.10 and 59.85 mg·dm^-3) and phosphorus (P, 9.56, 57.38, 95.62, 133.86 and 181.67 mg·dm^-3) fertilizers levels on the development and on nutrients uptake by Jacaranda decurrens subsp. symmetrifoliolata (carobinha), species of the Brazilian Cerrado, in a long term pot trial. The N and P addition together increased plant height and N concentration in roots. N and P also increased the P concentration and content on the roots in young plants, but in the older plants, isolated effect of both was stronger than their combined action. The N addition promoted branching, production of dry leaves and dry xylopodium, contents of K, Ca and P on the leaves, and N content on the roots. However, the N reduced xylopodium diameter, leaf area, and Mg contents in the young plants, but increased them in the older plants. The P addition increased stem diameter and dry biomass, P concentration and N content on the leaves, Ca content on the roots and also reduced N concentration on the leaves. However, the P addition increased Mg concentration on the roots in the young plants and reduced it in the older plants. In general, N levels ranging between 25.69 - 38.85 mg·dm^-3 and P levels between 84.39 - 109.23 mg·dm^-3 promote more effectively the plant development. Thus, N and P fertilization can promote the aerial development of plant and a differential allocation of nutrients between the carobinha tissues.
