The objective of this work was to develop and propose a procedure for modeling growth and yield of nonthinned eucalyptus clone plantations. The data used were obtained from 37 clones distributed in 4325 permanent plots from continuous forest inventories. Each clone contained at least three annual measurements. Five alternatives were studied for prognosis evaluation of clones with more than three permanent plot measurements. For the volumetric stock prognosis, the study showed that the model adjusted by modeling stratum was more efficient than the Clutter model. It could be concluded that growth and yield estimations for clones with less than three measurements can be performed using specific models per stratum or a general model. Such decision must, however, be evaluated by the modeling agent and the user, and a strong interaction between them is necessary.
