Liquid vermicompost as a biostimulant in chili pepper nurseries: Morphophysiological evaluation and impact analysis

Introduction: The present study addressed the need to find sustainable alternatives in agricultural production, highlighting the role of organic agriculture as an ecological agroecosystem management system. The importance of using natural inputs such as organic fertilizers to maintain soil fertility, protect biodiversity and reduce pollution was recognized. Among these inputs, vermicomposting was positioned as an effective technique for transforming organic residues into useful products for agriculture, with special interest in its application to horticultural crops such as chili peppers (Capsicum annuum L.) in the nursery stage. Development: During the development of the study, it was explained that vermicompost, being the result of the activity of earthworms and microorganisms, offered a stable product, rich in nutrients, and capable of improving the physical, chemical and biological conditions of the soil. It was described that this compost stimulated seedling emergence, as well as root growth, stem height and number of leaves, thanks to the release of hormonal compounds and beneficial microorganisms. The advantages of liquid vermicompost over synthetic fertilizers were also mentioned, as it is an accessible and environmentally friendly solution. Conclusions: The use of vermicompost leachate proved to be an effective agroecological alternative in chili bell pepper nursery production. It was concluded that it promoted early plant development, improved the substrate and reduced the time to transplanting, directly benefiting small and medium producers interested in sustainable agricultural systems.
