|metadata.revistascielo.dc.description:||Defining a suitable size and shape for experimental plots of candeia is an alternative for ensuring correct interpretations and consistent conclusions about the cultivation of this species. The objective of this work was to define optimal size, convenient sizes and suitable shape for experimental plots of Eremanthus erythropappus, for evaluation of main dendrometric characteristics in experimental plantations. To attain that, a uniformity trial was used containing 400 plants, all of which had circumference, height and volume measured. 31 combinations of size/shape were simulated for experimental plots. For determination of optimal size, three curvature methods and one method based on the segmented linear plateau model were used. For determination of suitable shape, the criterion of relative information and coefficient of variation was used. Convenient size was estimated by the Hatheway method. Results led to the conclusion that the size of experimental plots of candeia capable of allowing analysis of main dendrometric characteristics should be 60 useful plants, the most suitable shape being a rectangular configuration of 2×30 (rows × plants). Convenient size is a very flexible parameter and allows adaptations depending on the conditions, characteristics and limitations of the experiment in question.|
