Abstract
Fifteen clones of poplars, 2 clones of willows, and yellow poplar were used to evaluate the effects of 5treatments such as SCBLF (slurry composting and biofiltration liquid fertilizer), general slurry liquid fertilizer,chemical fertilizer, groundwater, and control (no treatment) on vitality, growth performance, and biomass production. Five cuttings for each tree species were planted in 3 replications. After planting cuttings, a coppice was induced by cutting off stems at 10cm above the ground. Data were collected for first growing season and trees were harvested at the end of October. Maximum mortality rate i.e. 96% was recorded in the cuttings treated with groundwater and minimum 92% with control (no treatment). In all tree species, sprouting of stump was not differ significantly among the treatments. Total nitrogen concentrations of leaves and stump sprouts were higher in the treatment of SCBLF than the control, 26.6% and 22.9%, respectively. Biomass production was highest in the stumps treated with chemical fertilizer, 1.98 Mg ha^-1 year^-1, and lowest in control (1.34 Mg ha^-1 year^-1).
