Root samples of sweet potato were examined for possible microbial association. Examination of roots from relatively open marginal soils exhibited evidence of mycorrhizal infection particularly the vesicular-arbuscular type. The capability of sweet potato for mycorrhizal association could be one of its adaptations for growth and productivity in marginal soils.
