Summary

When experiments are conducted on two crops in association significance tests are available for judging whether treatments are having different effects or not. If, however, differences are established, it becomes necessary to assess the various treatments in agronomic, dietetic or economic terms. Graphical methods are here advanced to aid such assessment, special attention being given to (a) the stability of recommendations when the monetary or other values of the two crops change from season to season, (b) the measurement of yield advantage of mixtures over pure stands, and (c) the maximization of yield when it is desired to produce the two crops in specified proportions. The relationship to competition experiments is discussed.
