- Abstract
The objectives of this research was to determine the optimum plot size and uniformity assay size for estimating the optimum plot size to evaluate the fresh weight of turnip (Raphanus sativus L.). Data were used from the fresh weight of 3,456 basic experimental units of 0.5m × 0.5m (0.25m²) and 46 uniformity assays sizes were planned. The optimum plot size was determined by the method of maximum curvature of the coefficient of variation model. The uniformity assay size, based on bootstrap with replacement of 2,000 samples, of each planned uniformity assay size, was determined. The optimum plot size to evaluate the fresh weight of turnip is the basic experimental units 4.82 (1.20m²). Uniformity assays with 225 basic experimental units (56.25m²) are sufficient to estimate the optimum plot size, in the bootstrap confidence interval of 95%, equal to one basic experimental unit.
