For instance, Table 12 shows that, in Gede, D. brandisii performed comparatively well in terms of culm
diameter (D=83%) and culm weight (DM=49%). However, on the site, the clumps of D. brandisii were very
sparsely populated with culms (AC=6). The high estimated potential yield (EY) of this species is due to the
weight of the culms, but under better conditions and with good management, it can have a much better overall
performance.
Bamboos are not created equal. In the family of woody bamboos, there are small, medium, large, and giant
species. Apart from good climatic conditions, sufficient sunlight and rainfall, each species needs enough space
to grow in order to reach its full size. This seriously has to be considered at the time of planting. In the KEFRI
trials; all bamboo species were treated equally and planted at the spacing of 5m x 5m. This spacing was
excessive for a small clumping species like T. siamensis, but insufficient for a giant like D. brandisii or large
species like D. hamiltonii and B. bambos. Depending on the purpose of the plantation, large tropical bamboos
with pachymorph rhizomes can be planted at distances of up to 10 m by 10m (100 clumps per hectare) to allow
for the establishment of huge clumps. If the plantation is intended for the production of edible shoots, spacing
can be reduced significantly, because the aim is to maintain thin clumps and harvest most of the shoots.
