Growth and Biomass Estimation of Eucalyptus urophylla provenance trials in degenerated Sal forest areas of Bangladesh

The growth and biomass production of twelve provenances of Eucalyptus urophylla planted in the degenerated sal forest areas of Bangladesh were studied at the age of 7 years at Charkai, Dinajpur and 7.5 years at Charaljani Silvicultural Research Station, Tangail District. The provenances showed significant differences in height and diameter (dbh) growth, though the final survival % was quite lower at Charaljani Station. However, the solo superiority of the provenances are not consistent in both the Research Stations. Among the 12 different provenances Mt. Wuko, Flores, IND-12897 produced maximum (14.9 t/ha/yr.) above-ground oven dry biomass at Charkai and Boka Afeng IND-11871 (12.4 t/ha./yr.) at Charaljani followed by Mt. Lewotoki, IND-13011 (11.7 t/ha./yr.) and IIwaki, Water Is, IND-11887 (11.4 t/ha./yr.) respectively.
