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 site 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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
