Abstract

In a controlled agroforestry system, this study evaluated the effects of vermicompost-silt mixtures (30:70, 40:60, and 50:50 ratios) on the growth and carbon sequestration potential of hybrid Paulownia elongata. Compared to other ratios and the control, the 50:50 treatment significantly (p ≤ 0.05) increased plant height (25 inches), stem diameter (0.87 cm), and biomass (13.22 g/plant). According to soil analysis, the 50:50 mixture had the highest carbon stock (6.61 g/plant) and improved potassium (582.67 mg/kg) and organic matter (1.12%) contents. These findings show that Paulownia growth and carbon capture are maximized by balanced vermicompost application, providing a sustainable method for agroforestry in nutrient-deficient soils.
