Espécies para arborização de pastagens.

ABSTRACT: The main of arborization of grasslands is the comfort supplied to the animals by the shadow of the trees, which not only increases the milk production but also improves the reproduction of the cows. In hot regions and shadowed areas, the grazing behavior of animals is changed resulting in better distribution of rumination during the day and more time for animals to rest. An experiment to select species for arborization of grasslands in the Cerrado areas was installed in Planaltina-DF, on a grassland of Brachiaria decumbens. In this experiment 21 species were evaluated. Based on tree height, trunk diameter, tree canopy and survival after 57 months, the best species for grasslands arborization were: Jacaré (Piptadenia gonoacantha (Mart.) J. F. Macbr, Tamboril (Enterolobium contortisiliquum (Vell.) Morong., Angico-do-cerrado (Anadenanthera falcata (Benth.) Speg., Eucalyptus citriodora Hook, Eucalyptus urophylla S. T. Blake, Mata-cachorro (Simarouba versicolor A. St. Hill.
