摘要：
This study aimed to evaluate the influence of edaphic and climatic factors on productivity of the first (R1) and second (R2) rotation eucalypt plantations managed under high forest and coppice systems, respectively. The data from 265 forest inventory plots of clonal plantations of a E. grandis x urophylla hybrid located in six municipalities of northeastern Bahia were used. We used the paired t-test, cluster analysis and multivariate regression for statistical analysis. The productivity of eucalypt coppice was narrowly related to the precipitation regime. At sites where rainfall was higher in R2, the productivity of this rotation was greater than R1. There was a marked effect of soil texture on site quality. At plots with sandier soils with lower soil water holding capacity, productivity of R2 was lower than that of
