Turmeric (Curcuma longa) fingers (Salem) sample was divided into three grades (I: 30–40 mm, II: 40–50 mm and III: 50–60 mm) according to its major dimension to study physical properties. Geometric properties viz., length, breath, thickness, arithmetic mean diameter, geometric mean diameter, square mean diameter, equivalent diameter, sphericity, aspect ratio, unit volume, surface area and shape factor were determined and found to be in the range of 30.18-48.54 mm, 9.72-10.62 mm, 5.12-6.38 mm, 14.72-22.84 mm, 12.72-14.64 mm, 23.21-26.54 mm, 0.24-0.38, 0.18-0.32, 1591-2904 mm3 772-1268 mm2 and 1.61-1.74 for Grade I, II and III respectively. The gravimetric and frictional properties such as bulk density, true density, porosity and angle of repose were 264-348 kg/m3, 1340-1358 kg/m3, 72.51-78.90 % and 35.57-37.90°, respectively. Also, coefficient of friction with surfaces namely plywood sheet were found to be in the range 0.82-0.88, respectively. The results of the study will help in designing the feed hoppers, metering mechanisms and planting equipment.
