Dissertação (Mestrado em Agronomia) - Universidade Federal de Goiás, Goiânia, 2014.http://repositorio.bc.ufg.br/tede/handle/tede/4685Brazil, has been feeling from a lack of technical guidance and ecological awareness in the exploitation of forest resources to meet the furniture industry, which has caused irreparable harm to species of great ecological value. The African mahogany source countries of the west coast of the African continent is one such tree species being used in commercial plantations, due to its high commercial value, the quality of the wood, its high yield potential and good adaptation to Brazilian climatic conditions. However, little is known about its water and a nutritional need which hinders adequate technical recommendation for this crop in the Cerrado region whose water deficit and the low fertility soils are very characteristic. Thus this study had the objective: evaluate plant growth in the first two years cultivation, irrigation and drip irrigation under different managements and topdressing. The research consisted of field experiments with plants of African Mahogany (Khaya ivorensis) spaced 5 x 5 m, experimental design was a randomized complete block design (RBD) with three blocks in split plots. For drip irrigated treatments were used 1, 2 and 3 emitters per plant with flow rates of 2 L.h-1, 4 L.h- 1 and 8 L.h-1, and irrigated treatments, microsprinkler, using 1 emitter for every 2 plants with different flow rates: 20, 30, 35, 40, 50, 58, 70 and 90 L.h-1, and no irrigation. For the following plots of fertilization doses were used 83.5 e 42.0; 167.0 e 83.5; 250.0 e 125.0; 333.5 e 167.0; 416.6 e 208.5 g.plant-1 of NH4SO4 and KCl, installments bimonthly in 5 applications from 4th to 12th month of planting.application/pdfAcesso AbertoManejo da irrigaçãoGotejamentoMicroaspersãoFloresta plantadaIrrigation managementDrip irrigation systemMicrosprinklerPlanted forestAGRONOMIA::CIENCIA DO SOLOENGENHARIA DE AGUA E SOLO::IRRIGACAO E DRENAGEMDissertação
