BIOLOGICAL INDICATORS OF RESILIENCE IN MIXED AND MONOCULTURE MUSACEAE PRODUCTION SYSTEMS

Abstract

Objective: To examine the impact of intraspecific diversity on the biological resilience and biodiversity of Musaceae production systems against pests and diseases in the Ecuadorian tropics, thereby improving the environmental sustainability of these agricultural systems. Theoretical Framework: Key concepts such as biological resilience, intraspecific diversity of Musaceae, and their relationship with soil health and pest and disease control were explored. The importance of mixed production systems versus monocultures in Musaceae agriculture was discussed. Method: An experimental design with completely randomized blocks was adopted in two locations (El Carmen and La Maná), comparing mixed and monoculture production systems. Three repetitions were used to collect data on the presence of arthropods, earthworms, and soil microorganisms, evaluating their diversity and quantity as indicators of biological resilience and environmental quality. Results and Conclusions: Mixed systems demonstrated greater biodiversity, particularly in the presence of Collembola, earthworms, and various beneficial microorganisms, indicating higher resilience and soil health compared to monocultures. Intraspecific diversity in mixed systems significantly contributes to the sustainability and resilience of Musaceae agroecosystems, suggesting a more resilient and ecologically sustainable production model for tropical agriculture. Originality/Value: This study provides empirical evidence on how intraspecific diversity and mixed production systems can enhance resilience and biodiversity in Musaceae crops, offering sustainable alternatives to face contemporary agricultural challenges in the Ecuadorian tropics.
