The papaya (Carica papaya L.) has great economic and social representation for Brazil. One of the most common fruit and consumed in the countries of Tropical America. Its cultivation presents new challenges every day and often requires experimental evaluations. One way to contribute to improving the quality of the experiments is to apply appropriate methods, based on objective rules that seek to minimize the experimental error and maximize the amount of information that can be obtained in an experiment. In this context it was aimed to determine the plot size in the production of papaya, through two experiments. In the first, there was a comparative assessment of the plot size in experiments with seedlings of papaya 'Golden Pecíolo Curto' by the method of maximum curvature of Meier and Lessman (1971), by the method of maximum curvature of the coefficient of variation according to Paranaíba et al. (2009), and by a method proposed, which includes the bootstrap simulation method of Lessman and Meier (1971). In the second experiment, we used the method of Hatheway (1961) when comparing the experimental designs completely randomized, randomized blocks and Latin square for papaya Baixinho de Santa Amália. The methods showed that the optimal size for seedlings 'Golden Pecíolo Curto' is five seedlings per plot, and that the new method for determining the viii optimal portion size with the use of bootstrap simulation with replacement in the method of maximum curvature of Meier and Lessman (1971) was similar to that seen for the method of maximum curvature of the coefficient of variation according to Paranaíba et al. (2009) by adding a new alternative methods of determining optimal plot size. The number of seedlings per plot for seedlings using the method of Hatheway (1961) is variable depending on the number of treatments and replications assumed precision, the character in question and the experimental design. It is recommended to use of nine seedlings per plot on experimentation involving production of seedlings of '‟Baixinho de Santa Amália‟ in plastic tubes.
