e0“The order of competitive ability that was apparent from these field and greenhouse studies, P. virgatum = R. pinnata > E. purpurea , could be partially explained by photosynthetic rates in relation to canopy light interception.”

- Association Single-species density reduced yields in greenhouse and field.
- Observation Early greenhouse mixture relative yields were up to 100% higher for all three species.
- Association Echinacea relative yield declined with Panicum later and in the field.
- Association Echinacea relative yield declined with Ratibida later and in the field.
- Association Panicum relative yield increased in the presence of Echinacea.
- Association Ratibida relative yield increased in the presence of Echinacea.
- Association Relative yields correlated between field and greenhouse at 80 and 120 days.
- Observation Panicum maintained higher net assimilation rates in the greenhouse.
- Observation Relative growth rates declined after 40 days, especially for Echinacea in mixtures.
- Observation Pure Echinacea stands had higher field light intensities than mixed stands.
