Bamboos

Bamboos (22)

Bamboo requires excess sunlight, they are clump forming and are more suitable for cultivation and grows very well in tropical and sub-tropical climatic condition.

Conventionally bamboo plantation in wider spacing of 4-5 m between plants results in 160-200 plants in one acre. This spacing is suitable for most of larger diameter bamboo such as Dendrocalamus giganteus, Dendrocalamus asper, Dendrocalamus hamiltonii, Dendrocalamus brandisii and also medium sized bamboo such as Bambusa balcooa, Bambusa nutans, Bambusa vulgaries, Bambusa tulda, Bambusa cacharensis, Bambusa bambus, Dendrocalamus strictus, Bambusa polymorpha.

Bamboo reaches maturity after 4-5 years under well managed plantation condition. Culms are marked for ages by different colour codes and selective culms are harvested after 4 years of culm growth. The cultivation practises, nutrition requirement, spacing between bamboo plants varies for each site.
