Abstract:
The determination of grains engineering properties serves an important base to design appropriate agricultural machines. Sixteen properties were determined using the standard methods in laboratory at moisture content of 11.1% to 28.2% on dry basis. The geometric mean diameter ranged from 3.62 to 4.8 with the sphericity ranges from 0.69 to 0.84. The density and rupture force significantly reduced with the increase in moisture content at p>0.01 and they are in the range of 701.86 to 855.6 kg/m³ and 43.92 to 92.16 N, respectively. The geometric size and frictional properties significantly increased with moisture content. The principal component analysis (PCA) has shown that 77.8% of the data revolves around the principal component one and 10.3% of data resonate on second component with manifest inter-variable patterns. The Pearson correlation coefficient showed the negative correlation between of length and the bulk density (r=-0.775, p=0.003) and positive correlations between length and friction properties.
