Handicrafts, thatching, basket making, kites, chicks for doors, house posts and mat making, floats for timber and rafts, edible shoots.
Culm length: 15-20 m
Culm diameter: 7-10 cm
Internode length: 25 to 60 cm
1. Distribution: Bihar, Bangladesh, Myanmar , West Bengal, Eastern India(Assam, Manipur, Mizoram and Tripura), Bangladesh and Myanmar.
2. Recommended for cultivation in the following site conditions:
Altitude- 400-500 m Soil type- fertile loamy soils common near streams Climatic condition- It prefers a tropical humid climate.
3.Planting material: Vegetatively propagated planting stock will be available and one year old planting stock should be preferred and procured from NBMrecognized nurseries or NBM high tech nurseries for out planting.
Availability: KFRI, Peechi, JNTBGRI, Thiruvananthapuram, Uravu, Wyanad
Tissue culture Plants: Not available commercially
Season of planting: Planting during the pre monsoon showers or prior to active monsoon.
Pre planting operations: Demarcation / fencing to be completed at least three months prior to planting. Weeding, at least 15 days prior to planting. Pit size & treatment.45 X 45 X 45 cm cubical pits, to be half filled and kept exposed to sun for top soil sterilization for about a month.
Planting: Along with the pre monsoon showers/prior to active monsoon the pits are completely filled and planted with one year old planting stock. The filled up soil to be compacted around the plant.
Spacing. Closer spacing of 5 X 5 m for edible shoot production, 9 X 9 m for timber production.
5. Soil/water conservation measures: Moisture/water harvesting trenches (60cm X 45cm X 30cm) are to be dug along the interspaces in the alternate rows of planting when planted in 6 X 6 m spacing.
6. Management of established clumps:
Cultural practices: All dead and dying culms to be cut and removed from the third year of establishment preferably in the months of November – February.
Fertilisation: To be carried out as per the advice of an expert after testing the soil once the clumps have established. Responds well to NPK and organic fertilizers like compost, vermi- compost and dried farm yard manure. Organic fertilizers recommended if grown for edibleshoots.
Irrigation: Responds well to irrigation however essential only during the first two years to ensure better establishment and quicker culm production. If grown for edible shoots watering ensures enhanced sprout production. Moisture retention through trenches should also be practiced. Plant protection measures: If managed properly with routine pruning, thinning and cleaning, (cultural practices) Bamboo usually escapes pest infestations. Proper sanitation measures should also be adopted for the control of fungal infections.
Thinning: Regular thinning and cleaning should be carried out from the 4th year of clump establishment. All dry, dead and drying culms are to be removed from the clump so as to create sufficient space in the clump for new sprouts to grow up straight. As a regular practice these operations are to be carried out every year probably prior to the winter months.
7.Harvesting. Culms (timber) should be harvested only during non rainy months. No current year culms are to be cut. For propagation about 20 % of two year old culms can be selectively cut from all portions of the clumps which can be made use of for vegetative propagation through rooting of culm cuttings. About 60% of the 3 year old culms and almost all of the 4th year culms can be cut and removed. However it is always better to retain a few older culms in the clump to serve as support for the younger newly emerging culms.
8.Flowering cycle: Not known. Estimated to be 45 years
