RESUMO
Devido &#xE0; car&#xEA;ncia de estudos agron&#xF4;micos com esp&#xE9;cies nativas e da import&#xE2;ncia do adequado fornecimento
de nutrientes &#xE0;s plantas, objetivou-se neste trabalho avaliar o efeito de doses de N e P sobre o teor e conte&#xFA;do
de nutrientes, bem como na efici&#xEA;ncia nutricional de mudas de barbatim&#xE3;o (Stryphnodendron polyphyllum),
em Latossolo Vermelho distrof&#xE9;rrico. O trabalho foi desenvolvido em vasos de 8 dm3
,
 mantidos em casa de
vegeta&#xE7;&#xE3;o. Foram estudadas quatro doses de N (0; 20,82; 41,64 e 62,46 mg kg-1 de N) e quatro doses de P
(0; 41,72; 83,44 e 125,16 mg kg-1 de P2
O5
), em esquema fatorial 4 x 4, no delineamento experimental de
blocos casualizados, com quatro repeti&#xE7;&#xF5;es. Decorridos 210 dias ap&#xF3;s a semeadura avaliou-se massa seca da
parte a&#xE9;rea e radicular e teor de macro e micronutrientes na planta; por meio desses dados foram calculados
os &#xED;ndices de efici&#xEA;ncia de absor&#xE7;&#xE3;o e utiliza&#xE7;&#xE3;o de nutrientes. Houve intera&#xE7;&#xE3;o significativa entre as doses
de N e P para os teores de P, K, Ca, Cu, Mn e Zn na parte a&#xE9;rea e N, P, K, Ca, Mg e Fe na raiz. Na parte
a&#xE9;rea das mudas, os nutrientes N e Fe foram influenciados somente pelo efeito isolado das doses de N, e o
teor de Mg pelo efeito isolado das doses de P. O conte&#xFA;do de todos os nutrientes, na parte a&#xE9;rea e na raiz, foi
influenciado significativamente pela intera&#xE7;&#xE3;o entre as doses de N e P. As m&#xE1;ximas doses proporcionaram
maior conte&#xFA;do de macronutrientes na parte a&#xE9;rea, exceto N e K. O conte&#xFA;do de micronutrientes na parte
a&#xE9;rea aumentou em fun&#xE7;&#xE3;o das doses de N e P e reduziu na raiz, exceto Fe. As mudas de barbatim&#xE3;o
mostraram-se mais eficientes em absorver N e Zn e utilizar P e Mg. Comparados ao conte&#xFA;do, o N e o
Ca foram os nutrientes mais acumulados nos tecidos da planta, contudo, os que apresentaram menor valor
(P e Mg) foram os nutrientes mais eficientemente utilizados.

ABSTRACT
Due to lack of agronomic studies with native species and the importance of an adequate supply of nutrients
to plants, this study aimed to evaluate the effect of N and P on the concentration and nutrient content as
well as the nutritional efficiency of barbatim&#xE3;o (Stryphnodendron polyphyllum) seedlings in Oxisol. The
study was conducted in 8 dm3
 pots and kept in a greenhouse. Were studied four doses of N (0, 20.82, 41.64
and 62.46 mg kg-1 N) and four doses of P (0, 41.72, 83.44 and 125.16 mg kg-1 P2
O5
) in 4x4 factorial in
randomized complete block design with four replications. After 210 days after sowing was evaluated dry
mass of shoots and roots and nutrient concentration in the plant, through these data were calculated the 
efficiency of absorption and utilization of nutrients. There was significant interaction between doses of N
and P to the concentration of P, K, Ca, Cu, Mn and Zn in shoots and N, P, K, Ca, Mg and Fe in the root.
In seedling nutrients N and Fe were influenced only by the isolated effect of N levels, and Mg content by
isolated effect of P levels. The content of all nutrients in the shoot and root was significantly influenced by
the interaction between doses of N and P. The maximum doses provided greater nutrient contents in shoots,
except for N and K. The micronutrients content in the shoot increased as a function of both N and P and
reduced the root, except Fe. The barbatim&#xE3;o seedlings were more efficient at absorbing N and Zn and using
P and Mg. Comparing the content, N and Ca were the nutrients that most accumulated on the plant tissues,
however, those who had lower (P and Mg) were the nutrients more efficiently used.
