Conteúdo: 	A method of determining the minimum size of plot has been described. Examples have been given of the inability to estimate herbage yields in a field of grass from two sizes of small test plots, where the size were chosen arbitrarily and not deduced by experiment. In addition, some aspects of herbage digestibility have been discussed. With such errors associated with herbage estimates, the problem of grazing trial comparison becomes even more difficult. The need for the training of animals adequately to the experimental conditions, prior to the start of an experiment, has been emphasized so that the errors of livewight assessment do not render grazing comparisons meaningless. the carry-over effects of pre-experimental treatments and conditions into the experimental period have been discussed and ilustrated. Data have also been given to show that carefully executed grazing trials can be quite useless if based on inadequate plot sizes for mmeasuring herbage productivities and for estimating uneaten residues.
