Abstract: A necessidade de desenvolver pesquisas referentes aos requerimentos nutricionais das espécies florestais, principalmente as essências florestais nativas da Amazônia, como o mogno, é inadiável, visto que as constantes explorações de espécies de alto valor econômico são cada vez maiores. Com o objetivo de avaliar o crescimento e o requerimento nutricional de mudas de mogno, foi realizado um experimento em casa de vegetação com 14 tratamentos. O delineamento experimental foi de blocos casualisados, com 5 repetiçõ… Show more

“…In a dystrophic Oxisol with clayey texture of the state of Amazonas, Souza et al (2010) studied the nutritional requirement of mahogany for macronutrients and obtained the following descending order: P>S>K>N. In the same soil, Tucci et al (2011) verified that fertilization with N (as urea) and P (as triple superphosphate) did not improve the quality caused negative effects ( Figure 5). Reduction in the RDM/ APDM ratio in climax species such as mahogany was observed by Resende et al (2000), who suggested that the increased availability of P caused a decrease in root growth and the consequent accumulation of dry matter in aerial part.…”

“…Considerando a ordem de acúmulo de nutrientes nas mudas, o P foi o nutriente com menor conteúdo, no entanto foi o mais eficaz em produzir massa seca. O P é citado por muitos autores (NICOLOSO et al, 2007;SOUZA et al, 2006;SOUZA et al, 2010, entre outros) como determinante no crescimento das plantas, uma vez que tem considerável importância no metabolismo do carbono, bem como na formação de açúcares fosfatados. Ao contrário do P, o Ca apresentou elevado conteúdo na planta, porém baixa eficiência de uso.…”

“…Differences were not detected for variables that expressed plant growth in relation to the different fertilization rates (Table 3). In studies with Brazilian mahogany and its nutritional needs, it was verified that the order of necessity follows P> S> K> N (Souza et al, 2010), which may explain the absence of a significant African mahogany response to potassium (K) and nitrogen (N), as these elements are not the most necessary in the initial growth of this plant. Increasing N doses of 0, 20, 40, 60, 80, 100 and 120 g N ton -1 of substrate increased Brazilian Mahogany (Swietenia macrophylla King) seedlings growth in terms of stem and root dry matter and plant height, up to the optimal dose of 61.5 g N Mg -1 .…”
