This study was conducted in Sekota District, a degraded dryland area, Northern Ethiopia. The objective of this study was to evaluate the potential growth response of Juniperus procera on Calcaric Cambisol and Eutric Regosol which are dominant soil types in the study area. Seedlings of Juniperus procera with the same age were planted in the field in June 2010 in a randomized complete design at the two soil types. Data on survival, height and root collar diameter were recorded every six months. As a result, height growth response was higher on Eutric Regosol than Calcaric Cambisol and were significantly (p<0.0039) different. Growth in RCD also reviled that there was highly significant (p<0.001) difference between the two soil types. High mean value of RCD was recorded in Eutric Regosol (1.12mm), while it was low in Calcaric Cambisol (0.96mm). The survival result also showed that 20% on Calcaric Cambisol and 45% on Eutric Regosol. Thus, the unfavorable nature of the soil in the area associated with other abiotic factors such as moisture stress and the long dry season which extended from seven to nine months in the study area, clearly explains the poor survival and growth response of this species. Keywords: Survival, growth response, Juniperus procera, dryland, Calcaric Cambisol, Eutric Regosol.
