| Abstract | ||||
| Some of the physical properties of the new rice drought variety (Sakha 107) in terms of principle dimensions (length, width, thickness), coefficient of contact surface and shape index-k were measured and calculated at four levels of grain moisture content (14.15, 15.11, 16.09, and 18.04%, w.b). The crack, head rice yield, broken grain percentages and whitening degree were also determined in term of milling quality at the same levels of grain moisture content and compared to the common rice variety Giza 177. The results of this study showed that, length, width and thickness of the new rice drought variety (Sakha 107) increased linearly with the increasing of grain moisture content, while, shape index-k and coefficient of content surface decreased generally with the increasing of grain moisture content. For the rice milling quality, the head rice yield and degree of whitening increased with the decreasing of rice moisture content and the broken rice percentage increased with the increasing the rice moisture content for both rice varieties Sakha 107 and Giza 177. In general, the data obtained from this study could help the designers and operators who deal with this new rice variety. | ||||
