A Half-yearly Peer Reviewed Journal of Bangladesh Forest Research Institute
Survival percentage and height growth of four types of planting propagules (stumps, poly
bag seedling, stumps in poly bag and direct seed sowing) of Gmelina arborea were studied at
Charaljani. Charkai, Keochia and Lawachara Silvicultural Research Stations located al different
regions of Bangladesh. There was no significant differences in the average survival percentage
among the polybag raised seedlings, stump planting, stumps in polybag and seeds directly sown in
the fields. The average survival percentage was 45% to 91% at four sites at the age of 2 years 4
months at Charaljani, Keochia, Lawachara and 1 year at Charkai Silviculture Research Station.
The difference in total height growth of four types of planting propagules was found statistically
significant. The highest height growth (263cm) was obtained in polybag raised seedling at
Charaljani followed by 105 cm at Keochia, 88 cm at Lawachara at the age of 2 years 4 months and
139 cm at Charkai at the age of 1 year after out planting. However, there was no differences in
height growth between the polybag seedlings and stumps in polybag at Lawachara Silviculture
Research Station.
