ABSTRACT This research aimed to evaluate the effects of irrigation and mineral nutrition on the growth and production of eucalyptus (Eucalyptus grandis) cultivated in the Triângulo Mineiro region, Minas Gerais, Brazil. The experiment was conducted at the Farm School of University of Uberaba, which has 850 m of altitude, in Red-Yellow Latosoil. Irrigated and non-irrigated treatments with different nutritional conditions (25, 50 and 100% of the recommended doses) were compared. The parameters of diameter at breast height and growth were evaluated during the period of five years of experimentation, the final productivity of wood was also determined at the end of that period. Even though results were statistically different throughout the years, at the end of the analyzed period it was observed that irrigated treatments showed higher biometric values as well as largest rates of mean annual increment. Proximity of values may have occurred due to excessive rainfall at the site, increasing availability of water for the non-irrigated treatments.
