It is important to know the production variability among experimental plots in a protected environment because this information reduces error and increases the reliability of the results. Therefore, the objective of this study was to characterize the spatial independence of fruit yield between plots of peppers and snap beans. Data on production uniformity were gathered from trials performed at the Department of Plant Science, Federal University of Santa Maria. Different plots sizes were created according to the number of plants in the crop row. To verify the randomness of the data distribution, we applied a sequence test between the plots within one line for individual and combined harvests. The use of ten plants per plot in experiments with peppers led to no randomness within the lines during the production of fruit fresh biomass. In experiments with snap beans conducted in a greenhouse, a plastic tunnel and by unprotected cultivation using plots with six or more basic units, 12 or more plants per plot produced random fresh biomass data for fruits within the crop row.Downloads
