Testing improved germplasm and/or agronomic practices to increase productivity requires accuracy and precision. The objectives of this stdy were to determine the optimum plot size (i.e., number of plants per experimental plot) and the number of replications to detect significant true mean differences in bunch weight (i.e., commercial yield) between treatments. Three uniformity trials of the cultivar Valery grown in Ultisols under two different management practices (alley cropping of banana with multispecies hedgerows and monocropping of banana in cleared land) and at two locations in the humid forest zone of sub-Saharan Africa were used. The methods of maximum curvature and comparison ofvariances were used to determine optimum plot size, while the number of replications was estimated by Hatheway's method. This statistical procedure considered an expected relative magnitude of differences between treatment means at a specific probability level and the relationship between the coefficient of variation and soil heterogeneity.  aAnthonotha macrophylla  aMycosphaerella fijiensis morelet  tAgronomy Journalgv.87, n.1, p.63-69, 1995.
