- A method for laying out triplicate plats for long-time field experiments is described. Three uniformity crops (corn in 1927, oats in 1928, and wheat in 1929) were harvested from an area involving something over 450 plats of 1/51 acre net each; and on the basis of correlation studies and other pertinent data, the relative yields of the corn and oat crops were used in establishing the location of replicated plats. A high correlation coefficient was obtained between the yields of wheat as determined from five rod rows removed from each plat and the yields determined from harvesting the entire net areas of the same plats.
