This study was carried out in a villaged called “Jurado” in Pasto-Nariño, situated at 1º5’38.17north latitude and 77º15’42.72” east latitude. The effect of associating the living fences with the production system of potatoes (Solanum tuberosum Lam) Var. Diacol Capiro, was found out. To meet that objective, an inventory of the forest species related to the living fences was performed, in order to find dasymetric variables such as height, habit and kind of top. As far as agricultural components are concerned, the following agronomic variables were taken into account: shoots emergence on the surface (DEB), number of shoots (NB), height of plants (H), flowering days (FD), number of tubercles (NT) and performance. The results showed some highly significant differences (p <0.01) in the interaction, the types of living fences per distance, in the variables such as shoot emergence on the soil surface, flowering days, number of tubercles and performance and significant differences (p <0.05) in the number of shoots and plant height variables. The number of emergence days and the number of shoots on the soil surface decreases when increasing the living fence distance and the number of tubercles, as well as the performance is higher when the plant is farther from the agroforestry arrangement.
