| The characterization of the deficiency symptoms of macronutrients and micronutrients on the growth of young plants of Mentha piperita were evaluated by the missing element technique. The experiment was carried out under greenhouse conditions at Universidade Federal Rural da Amazônia. The experimental design was completely randomized blocks with 12 treatments and four replicates and a total of 48 plots. The following treatments were tested: (C) Complete (macro-and micro-nutrients) and omissions of N, P, K, Ca, Mg, S, B ,Cu, Fe, Mn and Zn. The variables analyzed were: height, stem diameter, leaf area, and dry matter production. The omissions of nutrients induced morphological changes translated into deficiency symptoms. The omission of N and Ca showed the... |

| The aim of this study was to evaluate the development of young Swietenia macrophylla plants grown in Yellow Oxisol submitted to different liming and boron doses. Experimental design was completely randomized in factorial arrangement (|4x4|+1), with additional treatment (control), being 4 liming levels (0.5, 1.0, 1.5 and 2.0 t ha-1) combined with 4 boron levels (1, 2, 3 and 4 mg kg-1 of substrate). Parameters evaluated were plant height, stem diameter, stem dry matter, aerial part dry matter, root dry matter and aerial part dry matter/root dry matter ratio. The height of young Swietenia macrophylla plants was not influenced by liming and boron levels. Maximum yields of leaves and aerial part were obtained with doses of 1.57 and 1.44 t ha-1 of liming,... |
