The effect of age on some physical properties of Dura and Tenera cultivars of oil palm fruitlets were investigated. Fresh fruit bunches of Tenera and Dura were obtained from three different oil palm plantations at different age of cultivations such as 20, 30 and 50 years. Physical properties of their fruitlets were measured at different moisture contents using American Society of Agricultural Engineers (ASAE) standard. As the age increased from 20 to 50 years, mass of Tenera fruitlets increased

The sphericity of Dura cultivars increased from 80% to 87%, while that of Tenera fruitlets decreased from 81% to 64%. However, true densities of Dura and Tenera cultivars increased from 978.56 to 1180.32 kg/m 3 and 973.04 to 1160.14 kg/m3 respectively, while bulk densities increased from 720.50 to 882.25 kg/m3 and 680.41 to 865.92 kg/m3 respectively. The effect of age on mass, axial dimension, coefficient of static friction, true and bulk densities for Dura and Tenera cultivars fruitlets were significantly different (p<0.05) within and in-between cultivars except angle of repose and sphericity of Dura cultivar.
