The variety grown in each plot, and the coding of the replicates and lattice blocks, is shown in the field layout below: Each replicate contained exactly one plot for every variety. The experiment was set up to compare the performance of 25 varieties of barley and was designed as a balanced lattice square with six replicates laid out in a 10 x 15 rectangular grid. The example data are from a field experiment conducted at Slate Hall Farm, UK, in 1976 (Gilmour et al., 1995). We’ll consider two models: the balanced lattice square model and a spatial model.
