Abstract

The ideal conditions upon which the usefulness of the classical field trials depend rarely exist in nature. Nor can the conditions that actually exist be sufficiently formalized by current conventional practices to provide an adequate and consistently reliable interpretation of field trials. AI large number of trials for the same strains of Hannchen barley and other crops show that field trials can be freed from the procedures which attempt, by preselection and mathematical compensations, to arrange naturally irregular conditions according to a formalized mathematical model. Simpler and more accurate procedures, based on conditions as they actually exist, can be substituted. Thus the costs and time necessary for definitive field trials can be greatly reduced. Agricultural testing programs can be accelerated, with increased confidence in the reliability of the results.
