Phytosociological Study of Weed Communities in Zea Mays Cultivation: Contributions to Sustainable Development Goals (SDG'S) in the Ecuadorian Tropics

Objective: This study investigates the phytosociological characteristics of weed communities associated with Zea mays cultivation in different zones of the Ecuadorian tropics, aiming to identify and classify weeds to develop effective management strategies that enhance productivity while minimizing environmental impacts Theoretical Framework: The research is based on the concept that weeds, or 'noxious weeds,' significantly challenge maize cultivation by competing for essential resources. Theories related to plant competition and agroecosystem sustainability underpin the study Method: The methodology involves a phytosociological survey across five farms in Mocache, Ventanas, and Balzar. Using 45 quadrats of 50 x 50 cm in a zigzag pattern across one-hectare plots, weed species were identified and quantified. Data were analyzed to calculate biodiversity and importance value indices. Results and Discussion: Mocache had the highest weed population, while Balzar exhibited greater species diversity. Similarity indices, including Jaccard and Bray-Curtis, revealed distinct patterns in species distribution and dominance. These findings are discussed in the context of sustainable agriculture, highlighting the implications for weed management and acknowledging potential limitations due to environmental variability. Research Implications: The study provides insights into sustainable weed management in maize agroecosystems, contributing to strategies aligned with SDG 2 (Zero Hunger) and SDG 15 (Life on Land), promoting practices that enhance food security and biodiversity conservation. Originality/Value: This research offers a novel phytosociological analysis of weed communities in tropical maize cultivation, contributing to sustainable agriculture and aligning with global sustainability goals.
