Marigold (Tagetes erecta L.) is one of the most important flower crops in Mexico. Bacillus subtilis strain BEB-13 and Glomus fasciculatum Gerdemann & Trappe were employed to test their effect on marigold flower yield and quality. Marigold cultivar Alcosa was inoculated with Bacillus and/or Glomus at sowing and transplanting time. The number of inflorescences per plant, flower diameter, fresh weight, xanthophyll content and color were evaluated at the end of the crop production cycle. Bacillus and/or Glomus treated plants produced 14-24% more inflorescences than untreated plants. Although, the treated flowers had significantly higher fresh weight than controls, they did not differ in size. Bacillus improved flower clarity and yellow color but not xanthophyll content, and Glomus enhanced xanthophyll content but not color properties.
