    Evaluación de bioestimulantes foliares para incrementar el rendimiento en el cultivo de granadilla (Pasiflora ligularis) en el caserío El Obraje cantón Pelileo
    (2023-03) Carpio Rugel, Angy Lisbeth; Muñoz Espinoza, Manolo Sebastián
    Passiflora species are widely distributed in the Americas where they are very important, among which the sweet granadilla (Passiflora ligularis Juss.) stands out for its pleasant flavor and nutritional value, which allows to be commercialized in national and international markets. In order to increase crop yields, biostimulants have emerged as a sustainable alternative in recent decades. In the present study, the effect of the application of two foliar biostimulants on the increase in the yield of Passiflora ligularis (granadilla) was evaluated in El Obraje neighborhood, from canton Pelileo. Two types of biostimulants (Crop + Plus and Kelan Complex) were applied at a dose of 1.0; 1.5 and 2.0 ml/L in sweet granadilla plants at the beginning of flowering stage. The plants treated with Crop + Plus showed the maximum values in the petiole thickness, equatorial diameter and longitudinal diameter of the sweet granadilla fruits on the different sampling dates. Likewise, the increase in the application dose of Crop + Plus caused an increase in petiole thickness, equatorial diameter and longitudinal diameter reaching values of 5.21; 14.9 and 7.57 mm, respectively, which were higher than the control treatment (4.94; 11.69 and 5.9 mm). An effect of both the type of product and the dose used on the total ratio of sucrose dissolved in the passion fruit juice and on the weight of the fruits was also demonstrated, which varied from 17.6 to 20.9 °Brix while the fruit weight ranged from 74.3 to 120.0 g with doses 1.0 and 2.2 ml/L of Crop + Plus. According to the results, the use of Crop + Plus proves to be a viable option to increase the yield and quality of the sweet granadilla fruit.
