Synopsis Increasing plot length was more efficient than increasing plot width to reduce variation among plots for forage yield of alfalfa‐bromegrass mixtures. Estimates of optimum plot size and replicate number to detect differences among treatments were similar, using the coefficient of variability and Smith's b. Greater efficiency and less variation in the relative costs of plots of different sizes were observed for the lattice as compared with the randomized complete block designs.
