The Ecuadorian Amazon is the poorest region of Ecuador, particularly the province of Pastaza. The production of vegetables in the region is very limited and only established in the greenhouse. The pepper (Capsicum annuum L.) is a horticultural product very demanded, however, there is a criterion that cannot be grown in the area. Therefore, since 2014, the Center for Research, Posgraduate and Conservation of Amazonian Biodiversity (CIPCA), belonging to Universidad Estatal Amazonica initiated a research program to evaluate the adaptation of different horticultural species plants to conditions in the region, in order to contribute to food sustainability. The study consisted of determining the behavior of the Nathalie hybrid pepper crop, planted in greenhouse and open field conditions, for which a randomized block design was used. Productions, physiological and morphological indicators of the crop were evaluated and the results obtained were made a statistical comparison of means. The results suggest that better morphophysiological indicators are obtained when it was sown in the greenhouse, with height of 136 cm and a foliar area of 0.95 m2. However, the best productive and agricultural performance indicators were obtained outside the greenhouse, with 9 fruits per plant, with an average fruit weight of 975.80 g and an average yield of 6.42 kg m-2. This indicates the convenience of establishing this crop in the Ecuadorian Amazon without sow in the greenhouse.
