EFECTO DE LAS COBERTURAS ARBÓREA Y VEGETAL MUERTA SOBRE LA PRODUCCIÓN DE CAFÉ, EN LA ZONA CAFETERA NORTE DE COLOMBIA

In Pueblo Bello, a municipality located in the northern Colombian coffee zone, the application effect of dead plant coverage (mulch) on coffee was evaluated in two agroforest systems where the trees Inga edulis and Erythrina fusca were present. The trees were planted at a distance of 9 m x 9 m (123 plants per hectare) and there was free sun exposure coffee, which was established at a distance of 1.5 m x 1.5 m (4,444 plants/ha) in the three cases. The results indicate that the RFA interceptation average was 72% with shade of Inga edulis and 80% with shade of Erythrina fusca. Dead plant coverage does not have a meaningful implication on production. RFA interceptation from I. edulis and E. fusca meaningfully affects coffee production. The production average of free sun exposure coffee was 22.9% higher than the one under Inga edulis shade and 41.5% higher than the one under Erythrina fusca shade.
