Abstract

Poor ridging or hilling up and inappropriate tuber seed size for planting area are some of the factors affecting yield and marketable quality of potato production. Due to these facts, the experiment was conducted at Sinja and Shallo areas of Bale for three consecutive years with the objective of determining the effects of the tuber seed size and hilling up frequencies on yield and yield traits of Potato. Two seed forms (half and full seed size) and four level of hilling up including the control were combined in factorial arrangements and conducted using split plot design, tuber form was considered as main plot while hilling up frequency as sub-plot. The result of the study revealed that the highest total tuber yield was obtained from three times hilling up frequency followed by two times, but both means are statistically similar. Three and two times hilling up frequency had significantly increased total tuber yield by 24.7% and 15.5% over the control, respectively.
