a) Culm cuttings

The binodal cuttings are taken from 2-3 year old healthy clump by just cutting above the first node during March-April. The leaves and side branches are trimmed. Care should be taken not to injure the axillary  buds while removing leaves and branches. The cuttings should be transported to nursery either by wrapping in moist gunny bags or embedding in boxes containing moist saw dust. Two holes are made in the centre of the internode. About 100ml of 100 ppm NAA solution is poured into the culm cavity and the hole is closed by wrapping and tieing with a polythene strip (60 cm x  6 cm). The cuttings are placed horizontally across the nursery bed. The cuttings are covered with thin layer of soil (2-3 cm). Sprouted cuttings can be used for planting in main field.

b)  Layering
Some species are propagated by layers, the culm being particularly cut through near. The base, bent over and pegged down below the ground, would eventually result in development of roots and shoots at the nodes. The inter nodes are then cut through and the resulting, plants are separated and planted out. However, the resulted propagules by vegetative methods of production liable to flower with the parent clumps and that their life is short and uncertain.
