Abstract

Study was carried out at Forest College and Research Institute, Mettupalayam, Tamil Nadu, India using different age gradation viz., three, four and five year of Melia dubia wood samples collected from the plantations raised at Kollegal, Samraj Nagar District, Karnataka to evaluate the Physical and mechanical properties. Five year-old M. dubia wood recorded maximum density (500.20 kg m-3) and specific gravity (0.60). Among the age gradations five year old M. dubia registered maximum value for the parameters like static bending strength, modulus of rupture, modulus of elasticity, compression strength parallel to grain, Compression Strength perpendicular to grain, hardness, shearing stress parallel to grain, tensile stress parallel and perpendicular to grain, Nail-holding power, screw-holding power, brittleness, and cleavage strength parallel to grain. The current study confirmed the suitability of five year old wood as raw material for plywood, pencil, packing cases, and light furniture industry.
