Resumen
Two main soil management practices are generally used for soybean production: monoculture (MC) and crop rotation (CR). These strategies have different impacts on soil microbial communities. Among them, arbuscular mycorrhizal fungi (AMF) are well known to provide access to nutrients in a majority of cultivated plants. AMF communities have been shown to be more diverse in CR than in MC. Because AMF species differ in their effects on nutrition and development of plants, it could be expected that soil biota from different soil management practices affect soybean yield and quality. Therefore the objective of this study was to examine the combined effects of soil microbial communities and soil management practices (MC and CR) on yield, protein content, and oil quality of soybean grown under greenhouse conditions. The effects of three soil treatments, namely: sterile (S); microorganisms without AMF (MO); and microorganisms with AMF (AMF) were evaluated. These treatments were applied to soils from two crop management practices (CR and MC). Sterile soil promoted lower numbers of pods and seed weight per plant in MC but not in CR. AMF showed increased seed protein content (12?14%) whereas MO presented increased oil concentration (20?27%) (mainly within CR). Soybean grown with AMF from CR soil showed significantly higher amounts of oleic acid (21?25%), and lower linoleic acid (9%) when compared with other treatments. Findings from this study suggest that soybean yield and quality are affected by crop management practices and soil biota composition. Further, these parameters should be considered at the time of selecting agricultural strategies.
