ABSTRACT: 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.
