Crescimento da acácia-negra em resposta a aplicação de nitrogênio, fósforo e potássio. CERNE, Lavras, v. 19, n. 1, p. 51-58, jan./mar. 2013.0104-7760e- 2317-6342http://repositorio.bc.ufg.br/handle/ri/14415Due to the lack of information about Black-wattle fertilization, this study evaluated black-wattle plants growth in response to different fertilization levels of nitrogen, phosphorus and potassium six years after implantation. The statistical design used was a randomized blocks with trifatorial distribution. Total height (m), diameter at breast height (DBH) (cm) and stem volume with bark (m3 ha -1 ) were evaluated. Black-wattle showed a positive and significant growth response to N and P (interaction) fertilizations and absence for K. m To obtain the maximum development of black-wattle, for the soil and climate condition studied, it is required the use of the maximum dose of nitrogen (40.0 kg ha -1 N) and 78.9 kg ha -1 phosphorus, not requiring the addition of potassium.porAcesso AbertoAcacia mearnsiiAdubaçãoNutrição florestalAcacia mearnsiiForestry nutritionFertilizationArtigo10.1590/S0104-77602013000100007
