The raw sequencing data of 'Green manure increases peanut production through shaping the rhizosphere bacterial community and regulating soil metabolites under continuous peanut production systems'

Green manure (GM) as an alternative to fertilizer is useful for improving soil quality. However, whether GM treatment improves soil quality via regulating rhizosphere bacteria and soil metabolites remains unknown. In this study, we determined that several functionally significant bacterial phyla containing Actinobacteria and Acidobacteria, and genus Sphingomonas abundances were enriched in GM-applied soils, which are associated with nitrogen cycling. Consistent with the bacterial community results, metabolomic analysis revealed a strong perturbation of nitrogen- or carbon-related metabolisms in GM-applied soils. The significantly up-regulated beneficial metabolites including sucrose, malic acid, and betaines in GM-applied soils may contribute to overcome continuous cropping obstacle. In contrast to peanut continuous cropping, planting winter wheat and oilseed rape during the winter fallow period under continuous spring peanut production systems evidently improved the soil quality, concomitantly with raised yield by 32.93% and 25.20%, respectively. This study reveals that GM treatment is an effective strategy to overcome continuous cropping obstacle under continuous peanut production systems by improving nutrient cycling, soil metabolites, and rhizobacterial properties.
