Abstract	Non-toxic species of desiccated blue-green algae, or cyanobacteria, may offer potential for use as a fertilizer on irrigated crops. Here, the non-toxic cyanobacteria species Aphanizomenon flos-aquae (AFA), collected from Upper Klamath Lake, Oregon, was evaluated for use as a biofertilizer in a controlled experiment on Swiss chard “Bright Lights” (Beta vulgaris L. ssp. cicla L.). Two comparison groups were used in the study: group 1, fertilized with a commercially available synthetic fertilizer, and group 2, an unfertilized control. All plants were grown from seeds. With the exception of average root growth, the results found that both the synthetically fertilized and algae fertilized plants produced significantly higher growth rates than the unfertilized control group. These findings are consistent with other studies showing positive outcomes using live cyanobacteria in various cropping systems.
