Abstract:
A long-term field experiment initiated in the year 2018-19 at National Agricultural Research Project, was selected for conduct of present investigation during the year 2020-21 in order to determine the effect of different bamboo species on nutrient accumulation and distribution in different biomass components as a result of bamboo plantation grown on Entisol under semiarid climatic condition. In the average effect of bamboo biomass components, the nitrogen concentration was found highest in bamboo leaves (1.51% N), phosphorus and potassium concentration was significantly highest in bamboo branches (0.095% P and 0.64% K respectively), while, carbon concentration was numerically highest in bamboo stem (43.53% C). The bamboo species treatment, Bambusa nutans recorded significantly highest nitrogen uptake (457.83 kg ha^-1), whereas Bambusa tulda recorded the highest phosphorus and potassium uptake (49.70 and 409.77 kg ha^-1, respectively). The maximum carbon uptake of 27.83 t C ha^-1 was recorded in Bambusa nutans. All of the tested bamboo species had shown greater amounts of nutrient accumulation in above ground biomass, i.e. Stem > Branches > Leaves > Leaf-litter > Rhizome > Roots, due to maximum partitioning of total biomass towards above ground components. The results indicate that the relative proportions of nutrients accumulated in different biomass components in tested bamboo species vary greatly due to variations in elemental concentrations and biomass output after 2^nd year of bamboo plantation under semi-arid climatic conditions of Entisol.
