ABSTRACT

This study was conducted to investigate the physical properties of Jatropha
curcas seed (JCS) found in North West Ecological Zone of Nigeria. The seed
length, width, thickness, geometric mean diameter, sphericity, one thousand seed
weight, surface area, unit volume, bulk volume, true density, bulk density, specific
surface area, porosity, static angle of repose and coefficient of static friction
were the parameters investigated at 7.5% moisture content dry basis. The obtained
results range from 15.13–18.89 mm, 10.02–11.95 mm, 5.58–9.20
mm and 10.46–12.62 mm for length, width, thickness and geometric mean diameter,
respectively. The unit volume, bulk volume, one thousand seed weight, true density,
bulk density and porosity were found to be in the range of 79.00–85.00
cm3, 138.00–153.00 cm3, 535.30–611.90 g, 0.67–0.73 g cm-3,
0.37–0.42 g cm-3 and 38.41–45.70%, respectively. Sphericity, surface
area, specific surface area and static angle of repose investigated were in the
range of 56.15–72.37%, 3.44–5.01 cm2, 4.88–5.49 cm2 cm-3, and
23.03–28.66°, respectively. The coefficient of static friction against
the surfaces examined was in the range of 0.235–0.244, 0.415–0.455,
0.450–0.465 and 0.361–0.375 for steel sheet, ply wood, rubber and
aluminium, respectively. The properties will provide a data base for designing
equipment for production, handling, processing and storage of the seeds.

Key words: Jatropha curcas seed, physical properties.
