Replacement interaction diagrams offer a new approach in displaying results of interspecific competition experiments. They allow visual assessment of both actual and relative responses of two species in a replacement series to treatments arranged in a factorial array. Yield data are plotted on a semi‐logarithmic scale along the vertical axis. Treatments are arranged on the horizontal axis. The degree of interspecific interference or competition in mixed populations is best assessed by comparing the species response in a mixture with that in the monoculture. In competition experiments involving a number of treatment variables, replacement interaction diagrams highlight trends in treatment responses and allow some comparisions of responses between plant frequences.
