Abstract

Compares competitive interactions of three tallgrass prairie species. Yields were greater in mixtures than monocultures for all species early in the experiment. Yields of Echinacea purpurea decreased later in the experiment when planted with Panicum virgatum or Ratibida pinnata. However, the presence of E. purpurea increased the rate of the other two species. Differences in competitive ability may be partially explained by differing photosynthetic rates.
