Influencia de la fertilización en la producción y calidad de la pitahaya (Selenicereus undatus) en el Ecuador.

The pitahaya is an exotic fruit, whose cultivation in our country, in recent years, has reached significant importance, both in the local market and for export, being its main claimants the USA, Japan, and the countries of the European Union. All regions of Ecuador have proven to be good producers, being able to mention Palora, in the East, Pichincha in the Serranía, Guayas, Manabí, and El Oro on the coast. The present research work called Influence of fertilization on the production and quality of the pitahaya (Selenicereus undatus) in Ecuador, was carried out from the definition of the general and specific objectives focused on the characteristics of the crop and the levels of fertilization applied outside and inside the country. A broad theoretical support was presented, product of research and experiences already carried out inside and outside the country, which were collected and expressed in this thesis in a methodological way, describing and explaining everything concerning this subject, and for which the techniques used were bibliographic consultations, degree theses, specialized web portals, technical publications in high-impact journals. In terms of results, conclusions and recommendations, fertilization with nitrogen divided into four doses of 0; 40; 80 or 120 kg/ha, or the level of 80 kg/ha of nitrogen is best suited in a fertilization program. The application of phosphorus at levels of 0; 20 and 40 kg of P205/ha, or a level of 20 kg/ha of phosphorus is most appropriate in a fertilization program. The application of potassium and other micronutrients is recommended when preparing the soil for planting so that they contribute, mainly, to the quality of the fruit.
