Abstract: Browntop millet (Urochloa ramose L.) known as ‘korale’ in Karnataka is an annual warm-season grass often used as a forage crop gaining importance because of its nutritional qualities. Very fewer researches have been done so far on the millet. The research was conducted to determine the physical properties of the browntop millet. The physical properties were determined at moisture content 11.2 ± 0.16 (w.b). The mean values of length, width and thickness of the browntop millet were found to be 3.00 ± 0.21, 1.79 ± 0.10 and 1.15 ± 0.09 mm, respectively. The geometric mean diameter and arithmetic mean diameter were 1.82 ± 0.09 and 1.99 ± 0.1 mm, respectively. The mean weight of 1000 browntop millet seeds was 3.42 ± 0.14 g. The bulk density and true density were 601.17 ± 4.08 and 1305.47±95.5 kg/m3, respectively. The mean porosity, aspect ratio and sphericity were found to be 53.74 ± 3.23, 58.58 ± 3.84 and 59.82 ± 2.60%, respectively. The shape of the browntop millet was oval. The angle of repose was 27°47' ± 0.21 and the coefficient of friction for the three surfaces namely, Glass, Aluminum and Wooden Sheets were 0.62 ± 0.0009, 0.59 ± 0.0051 and 0.6 ± 0.0063, respectively. The terminal velocity was 7.2 m/sec. The tristimulous colour values (L*, a* and b*) were found to be 60.45 ± 0.44, 3.78 ± 0.06 and 14.71 ± 0.33, respectively. Hence this study helps agricultural and food engineers, designers, scientists and processors towards design of equipment and efficient process for browntop millet grain processing.
