A Half-yearly Peer Reviewed Journal of Bangladesh Forest Research Institute
EUCALYPTS were introduced in Bangladesh probably in 1930. The Bangladesh Forest Research Institute started trials on this species in 1963. It was established through research that the soil and climate of this country are suitable for Eucalyptus canialdulensis, E. brassiana and E. teriticomis. The research results and experience gained by the foresters of Bangladesh, India and some other countries show that eucalypts do not disturb the ecosystem even if planted in a large-scale.
Eucalypts can be planted for the production of timber, fuelwood, aroma, oil, gum and pulp. Therefore, this species may be highly economic if properly managed. Its only bad side is that the absentee farmers and rural landowners may find planting of eucalyptus more profitable and advantageous than the traditional agriculture. This may induce rural unemployment.
Pulping of bamboo-hardwoods in a mixture showed that H-factor required in soda + AQ and low sulphidity kraft + AQ was slightly lower than the calculated value from the mixture of the components. The total pulp yield for kraft15 + AQ was higher than the calculated value. But for soda + AQ it was lower from the theoretical value. The tensile strength of the pulp obtained in soda + AQ process was better upto 60% bamboo chips in the mixture. It showed superior quality with more than 60% bamboo in the component in low sulphidity kraft pulping. The bursting strength of the pulp decreased as the bamboo chips increased in kraft15 + AQ pulping. The tear strength behaved almost linearly with any proportion of bamboo chips with wood chips.
