Resumo: | The objective of this study was to evaluate the effect of nitrogen doses on the initial development and nutrition of Guanandi (Calophyllum brasiliense Cambèss) plants, a native Brazilian arboreal species. The experiment was carried out in a greenhouse, in plastic containers with capacity of 50 L of dystrophic red Latosol (oxisol). The experimental design used was completely randomized, with six treatments and four repetitions. The treatments consisted of five N doses: 0, 40, 80, 120 and 160 mg dm-3, and the control (with no fertilization or liming of the soil), where urea was used as the fertilization source. With the exception of the control, all the treatments received liming to elevate saturation by bases of soil of 60% and fertilization with 150 mg dm-3 of P2O5, 80 mg dm-3 of K2O. There were monthly analysis of the plant’s height and diameter of the connecting point of root and stem of the plant and at its 10 months age were also analyzed the leaves, stems, roots and total dry mass, the foliar area and the chemical analysis of leaves and stems. The N doses significantly affected the height, foliar area, stem and foliar dry mass data, observing a quadratic effect. The diameter and root dry mass data were affected on a negative linear way. The best growth response was obtained with the 40mg dm-3 N dose. |

O experimento foi realizado em casa de vegetação, em recipientes plásticos com capacidade de 50L de solo tipo Latossolo vermelho distrófico. O delineamento experimental utilizado foi inteiramente casualizado, com seis tratamentos e quatro repetições. Os tratamentos constituíram-se de cinco doses de N: 0, 40, 80, 120 e 160 mg dm-3, mais o controle (sem adubação e calagem), sendo a fonte de adubação utilizada a ureia. Com exceção do controle, todos os tratamentos receberam calagem para elevar a saturação por bases do solo de 60% e adubação com 150 mg dm-3 de P2O5, 80 mg dm-3 de K2O. Foram analisados mensalmente a altura da planta e diâmetro do coleto e aos 10 meses de idade: a massa seca de folhas, caules, raízes e total, a área foliar e a análise química das folhas e caules. As doses de N afetaram, significativamente, os dados de altura, área foliar, massa seca do caule e massa seca foliar, observando-se um efeito quadrático; já, os dados de diâmetro e massa seca de raízes foram afetados de forma linear negativa. A melhor resposta de crescimento foi obtida com a dose de 40mg dm-3 de N.Universidade Federal de Lavras (UFLA)2016-04-072017-08-01T20:16:07Z2017-08-01T20:16:07Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfCIRIELLO, V.; GUERRINI, I.
