Many agricultural experiments are conducted at more than one location and for several years. There is no standard reference which provides all of the details necessary for combining analysis of experiments with more than one factor. The objective of this paper is to present some complete analysis of variance tables to serve as reference for combining balanced experiments. Tables contains sources of variation, degrees of freedom, expected mean squares, and F-ratios for one factor, split-plot, and split-split-plot experiments combined over locations and/or years. The expectations and the F-ratios are given for random, fixed and mixed models.
