An analysis of some data from a replicated grazing experiment disclosed large variations among plots treated alike. Plot liveweight means in July appeared to have a bimodal distribution. The significance of such plot variation to economic analysis, and to the objectives of erazing experiments, is discussed. It is concluded the determination of an optimum stocking rate may be an unrealistic objective. The importance of studies of the symptoms of above-optimum grazing pressure is stressed. A policy of farm development and management decision-making is proposed for situations in which information on site productivity is inadequate.
