No definite cutting age is maintained for extraction of bamboo for pulp and paper industries in Bangladesh. In this study an attempt has been made to find out the optimum cutting cycle for muli bamboo (Melocanna baccifera) from the point of view of pulp yield and quality. The results show that bleachable grade of pulp is obtained at a lower cooking time with younger bamboos (9 months old) than those of higher age groups. The pulp yield at a given point of delignification is the highest w’th 21 months old bamboos- Physical strengh properties of the pulp are independent of age. Thus, it seems that 21 months old muli bamboo is better for pulping.
