The experiment was carried out in Aquidauana, MS, using an experimental design of randomized blocks in split plot scheme. The dendrometric attributes of the trees evaluated were height, diameter at breast height, volume, shape factor, taper, and dry mass production. The Grancam hybrid has the highest growth in height, and the Urograndis has the largest diameter at breast height. Drip irrigation provides an increase of 36.7% in the wood volume of eucalyptus hybrids when compared to those that were not irrigated. Keywords: taper, form quotient, drip irrigation, micro-sprinkler, wood volume.
