Vegetative Propagation of Maggar Bans (Dendrocalamus hamiltonii Munro):Effects of Planting Time, Spacing and Phophorus Application on Macro-Proliferation Behaviour under Open Nursery Bed

Dendrocalamus hamiltonii Munro was evaluated for the effect of month of planting, spacing and phosphorus application on survival, growth, rhizome-genesis, biomass partitioning and P-uptake in macro-proliferated stock. April planted propagules significantly excelled over July ones for all of these traits. Two to three times more dry biomass of stem, ischolar_mains, rhizome and underground biomass per sapling (g) production was recorded in April planted propagules as compared to propagules planted in July. P-uptake was also higher in April planted propagules than July ones. Spacing of 30 cm × 30 cm resulted in maximum growth, development, biomass production and biomass partitioning and Puptake than 30 cm × 15 cm and 15 cm × 15 cm spacing. Phosphorus application @ 5 g SSP per propagule resulted in maximum growth, development, rhizome-genesis, dry weight of stem and underground biomass. Higher dose i.e. 10 and 15 g SSP per propagule showed slight depressing effect.
