Extract

The design and analysis of rotation experiments present problems which are not encountered in annual experiments. The problems of design have been discussed by Yates (1949) and Stevens (1951 b). This paper is concerned with problems of statistical analysis. The experiment described is sufficiently general in its design for it to serve usefully as a basis of discussion of methods of analysis, both of the mean yields and of the measures of secular trend. It is shown that rotation experiments, without replicates within series, can be adequately analysed.
