Dry Matter Production in a Poplar <I>(Populus deltoides</I> Marsh) Plantation of Central Idmalayan Tarai

Abstract

Biomass and net primary productivity estimates of eight year poplar (Populus deltoides D-121 clone) plantation are described. Of the total biomass (176.4 t ha^-1) and net primary productivity (24.5 t ha^-1yr^-l) trees accounted for 96.4% and 89% respectively. Present estimates of biomass and NPP are higher than other fast growing poplar and Eucalyptus species of the region. Therefore, it is suggested in the favourable conditions of the Central Himalayan Tarai the trees of P. deltoides D-121 clone should be harvested in eight year short rotation period.
