Evaluación de bacillus SPP y trichoderma SPP como microorganismos potenciadores de la productividad en cultivos de pitahaya (hylocereus megalanthus), Los Bancos-Ecuador

Abstract

Yellow dragon fruit a is a very desirable for the national and international market, due to its organoleptic and nutritional characteristics, for this crop to reach optimal performance, adequate nutrition is necessary, which is not always achieved with management based on conventional agriculture. The trial was carried out in San Miguel de los Bancos - Ecuador, productivity-enhancing capacity of the treatments T1 (Bacillus spp), T2 (Trichoderma spp), T3 (Combination of Bacillus spp and Trichoderma spp) was evaluated. and compared with a control (Organic Fertilizer + Raizal), applied to plants in an edaphic and foliar manner, distributed in an experimental DBCA design during a productive period starting from sprouting to harvest. Statistical analysis was carried out using INFOSTAT software and significant differences were obtained between the treatments for the variable “weight of fruits” (p-value <0.0001), on the other hand, for the variables of number of flower buds, number of flowers, number of fruits, brix degrees and diameter of the fruits, there were no significant differences, so the implementation of microorganisms is an alternative to conventional management. The combined use of the microorganisms Bacillus spp and Trichoderma spp for management of the dragon fruit crop, prolongs the best cost benefit with a profit of $2.79 for every dollar invested, demonstrating the highest profitability in this treatment.
