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.
