At the time this experiment was conducted, the total size of the UNL greenhouse system was 10 rows by 20 columns. Positions marked with UP indicate pots filled with plants from an unrelated experiment, while positions marked with NA indicate pots that had no plants. The first complete replicate is shown in color, and the 4 incomplete blocks within the first replicate are marked in different colors. ^aMarks empty pots within the experimental design.
