Synopsis Based on uniformity trial data from double‐cross corn in Alabama, plots 1 to 3 rows wide and 10 to 15 hills long (1 plant per hill) were the most efficient, disregarding relative costs. A plot 2 rows wide and 10 to 15 hills long was considered the optimum size for general use. A basic unit of more than 5 plants may be advantageous in future experiments with corn uniformity data. There was only a small decrease in L.S.D. by increasing the replications from 5 to 6. The small gain in precision did not justify the use of the simple lattice instead of the randomized blocks design with 16, 25, or 36 entries.
