In Colombia, gulupa in recent years, is one of the exportable fruits with permanent increase production and demand, due to its positive impact on health, its nutritional and nutraceutical benefits, and its unique organoleptic characteristics. Consequently, gulupa growers in different areas of the country increase in quantity quality their production according to the requirements of the overseas market, which involves pre-harvest, cultivation, planning, distribution logistics and marketing. For almost a decade, technologies have been emphasizing the extension of post-harvest times due to the requirements of the established markets. It is even more important to evaluate these post-harvest characteristics in targeted areas and more precisely in the Amazonian region, in Putumayo area. This study was carried out in order to evaluate, fruit quality under an integrated fertilization system that included organic fertilizers like mycorrhizae 1 , humus 2 , vermicompost 3 compared to the control 4 with a chemical system fertilization (NKP) Fruit quality presented significant differences between the organic fertilizers treatments and the chemical fertilizers. Respiration rates, ethylene production (1856.9(1),1849.4(2),1822.4(3),1668. 8(4)) and total soluble solids were higher compared in organic fruit compared to the control. Additionally, color, texture, total titratable acidity, pH, sugars (fructose, glucose and sucrose and glycerol) and organic acids (malic, succinic, citric, and ascorbic acid) showed higher content, except the oxalic acid that was not detected while other authors found it in previous studies
