dc.descriptionWe studied the effects of farming systems and soil nematodes on the rhizosphere microbial profiles in three banana farming systems (conventional, barbecho and organic) compared with non-cultivated controls. Bacterial 16S Amplicon Sequence Variants (ASV) and fungal ITS1-2 OTUs were obtained by NGS from experimental fields in Costa Rica, each with a given farming system. Plant-parasitic nematodes included Meloidogyne, Helicotylenchus, Radopholus, and other species. The banana cultivation and, to a minor extent, the field management type influenced the rhizosphere ASV and OTUs abundances, with a higher diversity found in organic versus conventional crops, with the organic control as the most biodiverse. Diversity indices showed differences for the total number of individuals (lowest in conventional banana) and rare species (highest in organic controls). Fungi differed for the highest species richness in the organic controls. Soil variables affecting microbial abundance included low Fe content and acidic pH. Nematodes were associated with microbial taxa that were specific to each herbivore species or feeding group, with omnivores/predators influencing microbial profiles mostly in the organic crop and controls. The organic management had the lowest impact on the diversity of belowground nematodes and rhizosphere microbiome, highlighting its beneficial potential in sustainable banana production and agroecosystem resilience.
