Growth and Production of Eucalypto in Region the Médio Paraíba do Sul, RJ

ABSTRACT This study aimed to evaluate the production of Eucalyptus genetic materials, implanted in the town of Paty do Alferes, Rio de Janeiro. Were used four eucalyptus species, the hybrid Eucalyptus urophylla x E. grandis, from seedlings and two clones (yellow and white) of Eucalyptus urophylla x E. grandis. The region soil is water depleted from May to September. After planting, we evaluated the survival at 2 months and the diameter to the height of 1.30 meter from the ground, and total plant height at 18 and 80 months. In the latter measurement, six medium trees of each genetic material were abated to determine the volume and biomass of the wood. Eucalyptus grandis, yellow clone and Eucalyptus urophylla x E. grandis showed the best results, with the nominees for the formation of settlements in the region Médio Paraíba do Sul, RJ. Eucalyptus pellita showed lowest growth and yield.
