Abstract : This paper traces major features of the development of methods of field experimentation in agriculture from the work of the English agronomist Arthur Young in the 1960's to that of R.A. Fisher in the 1920's. Issues recognized by Young were the necessity that experiments be comparative, the importance of replication, the human tendency to bias, and the difficulties in making inferences beyond the results of an individual series of experiments.
