With the purpose of evaluating two guiding forms, simple and doble espalier, and three planting distances, 1600, 2000 and 2667 plants per hectare, an experiment was carried out at a blackberry production farm in the municipally of Cogua Cundinamarca. The trial was accomplished during two cultivation years, divided in a growing and a comercial production period. During this time, variables of yield, fruit quality and morphological aspects of the plant were measured. An experimental design of split plots was employed, where the main plot constituted the two guiding types and the secundary plots the planting distances. A total of three repetitions was used, with a changing experimental unit according to the evaluated distances. The variables inflrorescences per plant, fruit per plant and the leaf area Índex (LAI) showed significant diferences, favoring treatments with doble espalier and high densities. Gross production expressed in kg/ha, was superior in these treataments. The individual fruit weight showed no significant difference, while the titurable acidity was lower in fruits of plants distributed at higher distances. A high valué of total soluble solids was obtained, indicating the necessity of evaluating in mayor depht coid climate crops, which could offer fruits of exportable and industrial quality. It was concluded that the highest number of plants per hectare and the espalier or doble T quiding form, constítute the advisable production system under the evaluated conditions.
