RESUMO
Objetivou-se, neste estudo, avaliar os requerimentos nutricionais e o efeito da limitação de nutrientes no
desenvolvimento de mudas de baru (Dipteryx alata Vogel) utilizando a técnica da limitação nutricional. O
ensaio foi estabelecido em delineamento inteiramente casualizado com 12 tratamentos e oito repetições. Os
tratamentos adotados foram os seguintes: completo 1 (C1 - adubado com N, P, K, S, B, Cu, Zn e calagem),
completo 2 (C2 - adubado com N, P, K, S, Ca, Mg, B, Cu, Zn, sem calagem), tratamentos completos com
omissão de um nutriente por vez (completo 1 - N, completo 1 - P, completo 1 - K, completo 1 - S, completo
1 - B, completo 1 - Zn, completo 2 - Ca, completo 2 - Mg, completo 1 - calagem) e controle (solo natural).
Aferiu-se o diâmetro e a altura das plantas, separando-as em parte aérea e sistema radicular. As mudas
foram secas, pesadas, moídas e foi determinado o teor de nutrientes na matéria seca da parte aérea. De
acordo com os resultados, as limitações de S e B não afetaram o crescimento das mudas de Dipteryx alata.
P e N foram, de forma geral, os nutrientes que mais limitaram o crescimento das mudas de baru. A sequência
de exigência nutricional apresentada pelas mudas de baru, considerando a produção de biomassa seca da
parte aérea, em ordem decrescente foi: P = N &gt; Ca = Mg = Zn = K = S = B.

ABSTRACT
This study was conducted with the objective of evaluating the nutritional requirements and the effect
of nutrient limitation over the development of baru seedlings (Dipteryx alata Vogel), using the nutrient
limitation technique. The trial was established in a completely randomized design, with 12 treatments and 8
replicates. The adopted treatments were the following: complete 1 (C1 – fertilization with N, P, K, S, B, Cu,
Zn and liming), complete 2 (C2 – fertilization with N, P, K, S, Ca, Mg, B, Cu, Zn, with no liming), complete
treatment with the omission of a nutrient at a time (C1-N, C1-P, C1-K, C1-S, C1-B, C1-Zn, C2-Ca, C2-Mg,
C1-liming) and control (natural soil). We assessed plant height and diameter, and separated them into shoot
and root system. The seedlings were dried, weighed, ground for the determination of nutrient content of the
shoot dry matter. According to the results, the limitation of S and B did not affect the growth of Dipteryx
alata seedlings. In general, P and N were the nutrients that most limited the growth of Baru seedlings. The 
sequence of nutritional requirements presented by the Baru seedlings, in decreasing order, considering the
production of shoot dry biomass, was: P = N &gt; Ca = Mg = Zn = K = S = B.
