Resumo
The present work aimed to evaluate the seasonal increment in diameter of Eucalyptus grandis trees for 24
months and its relationship with the climatic variables and fertilization with nitrogen and with sewer mud.
The trees were planted in the spacing of 3 x 2 m and fertilized with nitrogen (planting, 6, 12, 18 months) and
sewer mud (planting and 8 months). 20 trees were selected by treatment according witch the distribution of
basal area and installed dendrometer bands at a 1.3 meter. The results showed a clear effect of the climatic
variables on the seasonal increment in diameter of trees, being observed a delay period (lag) of 28 days
for the answer of the trees in relation to the climatic variables. Regading to the fertilization effect, it was
observed that the increment of trunk diameter was higher in the eucalypt trees with organic in relation to
mineral fertilization with nitrogen.
