    This research was conducted due to the decline in natural populations of mortiño (Vaccinium floribundum Kunth). The constant extraction of fruit and plant material, coupled with deforestation, ecosystem fragmentation, páramo burning, and the use of branches for floral arrangements, has led to a progressive decrease in natural mortiño populations. The research aimed to evaluate the adaptation of mortiño (Vaccinium floribundum Kunth) to the application of three organic materials (chicken manure, guinea pig manure, and cattle manure) at three different doses, under controlled conditions at the Salache Campus of the Technical University of Cotopaxi. A completely randomized design with a 3 × 4 factorial arrangement was used, evaluating agronomic variables such as rooting percentage, number of branches, length of primary branches, number of secondary branches, plant height, stem diameter, humidity, temperature, pH, and electrical conductivity, over a period of four months. The establishment rate reached 91.67%, demonstrating adequate initial adaptation of the plants to the cultivation system. Statistical analysis showed no significant differences (p > 0.05) between treatments in the evaluated growth variables; however, the means obtained allowed us to identify treatment m3d3, corresponding to bovine manure at a dose of 2.25 kg per 25-liter pot, as the one with the best agronomic performance. This treatment presented the highest values in primary branch length (4.9 cm), plant height (4.9 cm), stem diameter (3.9 mm), number of secondary branches (1.46), substrate moisture (67%), temperature within the optimal range (14–22 °C), pH (4.5), and electrical conductivity (1.07 dS m⁻¹). The improved performance is attributed to the contribution of essential nutrients from the bovine manure, mainly nitrogen, phosphorus, potassium, and calcium, which promote vegetative growth and root development. The aforementioned economic analysis of the treatment required a total investment of USD 173.21, of which 92.38% corresponded to labor and 7.62% to direct materials, with peat (2.50 kg) being the most expensive input in the m3d3 treatment. It is concluded that the application of bovine manure at a dose of 2.25 kg constitutes the most favorable alternative for the initial adaptation of mortiño under the evaluated conditions, providing technical information for future adaptation and conservation programs for this native species of the Ecuadorian Andes.
