Abstract: This paper describes the results from a bamboo plantation (i.e. D. asper, D hamiltonii and B balcooa) grown in the Bamboo based Agroforestry system at Dr YS Parmar University of Horticulture and Forestry, Nauni - Solan under mid hill conditions of HP. Bamboos with a high production and wide utilization has been planted in large scale in southern China and India but little information about bamboo nutrition is available. The objective of this study was to reveal the dynamics of nutrition with growing time and the distribution of nutrition in different organs. It was found that the nutrition concentration of the whole plant generally declined with time owing to a dilution effect with the result of quickly increasing the biomass. The leaf, branch, stem, root and rhizome concentration of nitrogen (N), phosphorus (P), and potassium (K) changed regularly, generally declined with the age. The concentrations of calcium (Ca) and magnesium (Mg) in bamboo leaf, branch, stem, root and rhizome appeared to be opposite to those of N, P, and K in corresponding plant parts. The abundance of nutrition in leaves, branches, and stems of bamboo followed the order of N>K>Mg> P > Ca, K>N>Mg>P>Ca, and K>N>Mg> P> Ca, respectively. However in below ground parts the nutrients in root and rhizome of bamboo followed the order of N>K> P > Mg > Ca and N> K> Mg > P > Ca respectively.
