Resumen
El plátano es una de las frutas tropicales más importantes a nivel mundial, porque es alimento básico para millones de personas de escasos recursos. En la zona cafetera de Colombia la zona productora de plátano más importante del país (Departamento del Quindío), ha perdido en los últimos años su capacidad productiva y sostenibilidad por falta de tecnología eficiente, económica y ecológica paradesarrollar estrategias de prevención y manejo de enfermedades para garantizar la sostenibilidad del cultivo. En este trabajo se evaluaron diferentes alternativas biológicas como lixiviados de residuos de plátano, micorrizas comerciales, lombricompost y la técnica Fertilización Bio Orgánica (FBO) para el control de nemátodos fitoparásitos; se establecieron ensayos en parcelas experimentales en campo usando seis plantas por cada unidad experimental, se evaluó la macrofauna y la agregación del suelo, las poblaciones de nematodos (suelo y raíz), para micorrizas colonización, número de esporas , micelio externo, para variables asociadas al crecimiento (No. de hojas, Diámetro de tallo y altura de planta)y la producción.
//Abstrac: Banana is one of the most important tropical fruits worldwide, because it is a staple food for millions of poor people. In the coffee zone of Colombia’s banana-producing area’s largest country (Quindio), has lost in recent years their productive capacity and sustainability due to lack of efficient technology, economic and ecological strategies for prevention and disease management to ensure sustainability of the crop. In this work, various biological alternatives as leachate from waste banana commercial mycorrhizae, vermicompost and technology Bio Organic Fertilizer (FBO) for the control of plant parasitic nematodes; trials were established in field plots using six plants per experimental unit was evaluated macrofauna and soil aggregation, populations of nematodes (soil and root) to mycorrhizal colonization, number of spores, external mycelium, variables associated with growth (No. of leaves, stem diameter and plant height ) and production.
