The experiment was conducted out in private farm during 2012- 2013 and 2013- 2014 agricultural seasons, to study the effect of plant spacing and cutting of tuber on quality characteristics of potato (Desiree cultivar). The experiment included 6 treatments, which were the combination between two plant spacing (30 and 15 cm between hills) and three treatments of tuber cutting complete tuber cutting on to two parts and four The six treatments were arranged on randomized complete block design with four replicates. The results are summarized as follows: 1-      The combination of Cutting tuber in to two parts with planting space 30 cm had no significant effect for all characters, but their was significant decrease in all studied characters, when tuber were cutted in two parts and planted at 15cm spacing compared to control treatment during 2012- 2013 and 2013- 2014 agricultural seasons. 2-      Cutting tubers in four parts with planting spacing 30cm or 15 cm gave significant decrease in all studied characters compared to control treatment during 2012- 2013 and 2013- 2014 agricultural seasons. 3-      There was no significant decreasing effect on all. These is studied characters when potato tuber was planted with compete tuber (without cutting) compared to control treatment 30 cm.
