Abstract
We study the effect of implements on the physical properties of the produced potato tubers. These potatoes were classified as grade A. There was a significant difference in tuber shape index among the tillage implements. The results showed that the tuber weight of fresh potatoes was 179.28-201.64 g, and the bulk density was 1.066-1.068 g/cm(3). There were no significant differences among the physical properties. Thus, it is appropriate for a farm to select any of the studied tillage implements that are available.
