    The systems agroforestales are guided to allow productive activities under conditions of high fragility, with degraded natural resources, by means of an efficient economic administration, altering to the minimum the ecological stability, that which contributes to reach the sostenibility of the production systems. The investigation was developed in the place Galápagos, canton Echeandía, Bolívar province, to an altitude of 910 m, temperature average of 22oC, precipitation average of 1800 mm. The objectives were: i) Settle down and to evaluate two systems agroforestales agronomical with base the cultivation of cocoa; ii) Evaluate the morphological characteristics and to determine the growth that presents the cultivation of cocoa in each system agroforestals cocoa in the first year of investigation. It was used two systems agroforestales: Triplaris guayaquilensis Weddell and Inga edulis with base of cultivation cocoa. Was carried out statistical analysis to determine the minimum value, maximum, average, relative frequency and percentage of the frequency. The evaluation was carried out to the beginning, 6 and 12 after established the systems agroforestals. The results of this investigation samples that the morphological and agronomic characteristics of the plants of cocoa inside the two systems agroforestales in this area agroecológica, were different for the main evaluated variables. At the end of the investigation the plants of cocoa in the system Triplaris guayaquilensis Weddell, reached a height average of 95,83 cm, with a maximum of 100 cm and the minimum 93 cm. In the system Inga edulis, the height average was of 86,50 cm, the maxim was 101 cm and the minimum 50 cm. To the 12 months, the minimum value and maximum of the diameter of the shaft of the base cultivation inside the system Triplaris guayaquilensis Weddell, it was of 0,45 and 0,69 cm. In the system Inga edulis, the diameter average was of 0,56 cm, a minimum of 0,45 cm and a maximum 0,69 cm. The plants of cocoa of the system Triplaris guayaquilensis Weddell to the 12 months they reached diameter of glass of 69 109,00 cm and in the system Inga edulis was of 103,44 cm. In the system Triplaris guayaquilensis Weddell one had 98,00% apprehension and 91,00% of survival of plants of cocoa; in the system Inga edulis registered an apprehension of 95,00% and a survival of plants of 87,00%. The incidence of Broom Trims glass (Crinipellis pernicious) and Ant arriera (Atta cephalotes) in the base cultivation in the two systems agroforestales, he/she registered respectively to the 6 months with an average of 9,00% and 69%. The systems agroforestales allow us to achieve a stable agricultural production, the forest species by themselves provide other benefits like: food source, wood and they improve the fertility of the floors like it is the case of the guabo
