          Abstract

          Se evaluó el efecto de la aplicación de 6 dosis de compost más un testigo, en interacción con la aplicación ó no aplicación de nematicida, sobre la dinámica de las poblaciones de microorganismos del suelo (bacterias, hongos y actinomicetes), las poblaciones de nematodos fitoparásitos y la salud del sistema radical en el cultivo del banano. Los resultados obtenidos no indicaron diferencias en las poblaciones de microorganismos con respecto a las diferentes dosis de compost ni con respecto a la aplicación ó no aplicación de nematicida. En cuanto a los índices de diversidad biológica, en las poblaciones de hongos, no se obtuvieron diferencias de acuerdo con las dosis de compost, pero sí en lo referente a la aplicación ó no aplicación de nematicida, siendo mayor en el primer caso para la variable riqueza. La sanidad del sistema radical no difirió con las diferentes dosis de compost ni con ó sin nematicida, solamente hubo diferencias según los muestreos realizados. Por último, las poblaciones de nematodos fitoparásitos no presentaron diferencias debidas a las dosis de compost, a excepción de Pratylenchus. Con respecto a la aplicación de nematicida, todas las poblaciones fueron mayores en el área donde no se aplicó nematicida.

          Translated abstract

          The effect of implementing 6 doses of compost plus a control, interacting with the nematicide application or non-application, on the dynamics of the soil microorganisms population (bacteria, fungi and actinomycetes), the phytoparasite nematode populations and the root system health of the banana crop, were evaluated. The results did not show any difference in microorganism populations in relation to the different compost dose or to the nematicide implementation or nonimplementation. Regarding the biological diversity idexes, in the fungus populations no differences were obtained according to the compost dose, but they were in regard to the nematicide application or non-application, being larger with the richness variable in the first case. The root system health did not differ with the different compost doses, nor with or without nematicide; there were only differences depending on the sampling carried out. Finally, the phytoparasite nematode populations did not show any difference due to the compost dose, except for Pratylenchus. As regards to the nematicide application, all populations were larger in the area where no nematicide was applied.
