Details
Heath says each plot is .011 acres. An acre is 43560 sq ft, so each plot is 479.16 sq feet, which rounds to 480 sq feet. If Heath Figure 3-1 is correctly shaped, each plot is approximately 12 feet x 40 feet = 480 sq ft. Each plot had "some 350" plants. Harvested 1958.
Location if the experiment is unknown, but Heath was Professor of Horticulture at the University of Reading, United Kingdom, so it is likely the experiment was conducted in the U.K.
