Abstract
This research is aimed at evaluating the effects of irrigation and mineral nutrition
on the growth and production of eucalyptus (Eucalyptus grandis) cultivated in
the region of Triângulo Mineiro. The experiment was conducted at the Farm
School of Universidade de Uberaba, which has 850 m of altitude, in redyellowish
Latosoil. Irrigated treatments and non-irrigated treatments with
different nutritional conditions (25%, 50% and 100% of the recommended doses)
were compared. It was evaluated the parameters of diameter at breast height and
growth in a period of five years of conducted experiment; 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 the biggest biometric values as
well as the biggest rates of annual medium increment. Proximity of values may
have occurred due to excessive rainfall at the local, making water more available
to the non-irrigated treatments.
Keywords: commercial wood, irrigation, fertilization.
1 Introduction
According to FAO, Brazil is the second most forested country in the world with
almost 477.77 millions of hectares, and the fourth country with the biggest area
dedicated to plantation forestry. However, the country lacks adequate
information and functional mechanisms. The usefulness of eucalyptus is evident:
virtually all parts of the tree are exploited [3]
