Abstract

Macronutrients concentrations in leave, stem, and root tissues of Schizolobium amazonicum Herb. were determined under greenhouse conditions using the missing element technique. The experimental design was a completely randomized block with four replications and 13 treatments. Seedlings 0.05–0.10 -m high were planted into 3 L pots filled with nutritive solution. Based on the concentrations of macronutrients in the leaves of the complete and the deficient treatments, suitable and deficient levels (g kg-1) of macronutrients for S. amazonicum are: a) suitable: 4 for P; 15 for K; 40 for Ca; 4 for Mg; and 3 for S; 33of B; 5 of Cu; 540 of Fe, 88 of Mn; and 71 of Zn; b) critical: 1 for P; 4 for K; 8 for Ca; 1 for Mg; and 2 for S; 31 of B; 4 of Cu; 140 of Fe; 38 of Mn; and 24 of Zn.
