The growth and biomass production of twelve provenances of Eucalyptus brassiana were studied at the degenerated sal forest areas of Madhupur, Tangail. The trial assessed at the age of seven year showed poor survival (18 – 33%). The provenances also showed both height and diameter growth differences but the differences were not significant. Considering the above ground biomass estimation, Provenance No. 13411, Weipa, Queens land showed the highest productions both for mean trees (44.4 kg/tree) and per hectare basis (52.6 t/ha) followed by Provenance No. 13396 E. Morehead, PNG.
