%X due 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.
