    Description

    In Portugal, several eucalyptus spacing trials cover a relatively broad range of experimental designs: trials with a non-randomized block design with plots of different size and number of trees per plot; trials based on a non-systematic design in which spacings were randomized resulting in a factorial arrangement with plots of different size and shape and equal number of trees per plot; trials based on a completely randomized block design with different plot sizes and different numbers of trees per plot. Limitations and advantages of these experimental designs, when applied to Portuguese climatic and edaphic conditions, are discussed based on theoretical principles and empirical observations. This analysis suggests that, when the main objectives are to improve databases and to sample extremes of stand conditions for modeling purposes, more importance should be placed on the practical consequences in the prediction of stand characteristics than on the theoretical aspects.
