| description | The objective of this work was to evaluate the effect of macronutrients doses upon the growth and quality indices of <em>Peltophorum dubium</em> seedlings and to determine the recommended doses for them to establish a suitable fertilization program. In the paper, carried out in a greenhouse, samples of ‘Red Yellow Ultisol’ were used, removed from the layer below, 20 cm deep, as a substratum. The experiment was designed in a Baconian Matrix, and three doses of the six macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) and two additional treatments were evaluated, one with reference doses and the other one without the addition of nutrients. The entirely casual design was adopted, with four repetitions. The morphologic parameters and quality indices of seedlings were analyzed. Through the orthogonal contrasts, a significant response of all the variables studied was verified related to the macronutrient applied, except for the relation height/diameter (H/D) in the treatments with Ca, P and S. It was not verified response to Ca application for most characteristics evaluated, unless for the relation of the aerial part height per aerial part dry weight (H/MSPA) and aerial part dry weight per root dry weight (MSPA/MSR). The recommended doses were of 600 mg dm<sup>-3</sup> of P, 150 mg dm<sup>-3</sup> of K, 0,50 cmol<sub>c </sub>dm<sup>-3</sup> of Mg and 50 mg dm<sup>-3</sup> of S. Based on this work, further studies are suggested with N and Ca, for seedlings production of the studied species using from the layer below 20 cm deep of the ‘Red Yellow Ultisol’ as the substratum.<br /> |
