Abstract

This paper aimed to evaluate the production of dry matter in leaves, stems and roots, to identify the effect of nutritional deficiencies, and to describe visual symptoms of macro and micronutrients deficiencies in Shizolobium amazonicum Herb. Seedlings were grown in a greenhouse experiment in 13 treatments. The deficiencies due to macro and micronutrients markedly decreased the production of dry matter. The Schizolobium amazonicum showed different responses to treatments. In the first few weeks, the seeds were able to supply P in the necessary amount but, due to fast growth rates, N was the limiting factor at this stage. Nitrogen and Fe were the most limiting and Mg, S, and Cu, were the least limiting to growth. Sodium was also less limiting to growth.
