Abstract: It is important to determine optimal experimental plot size in order to ensure accurate results and correct decision making. There are no studies of this nature for lima bean cultivation. As such, the aim of this study was to determine the optimal plot size to estimate lima bean yield in family farming and experimental areas, combining the number of treatments, repetitions, and accuracy levels. Experiments were conducted in two 12m × 16m plots, each subdivided into 192 basic units (BUs) measuring 1m2. Bean weight was assessed in each of the units (g). Smith’s index of soil heterogeneity and optimal plot size were estimated using the Modified Maximum Curvature Method and Hatheway’s Method. The index of soil heterogeneity was higher than 0.7 for all the variables analyzed. Plot size between 10m2 and 15m2 is considered efficient in estimating lima bean weight. These first estimated optimal plot sizes will allow researchers and farmers who work with the crop to obtain more robust yield estimates.
