LIMA, Juliana Firmino de; PEIXOTO, Clóvis Pereira; LEDO, Carlos Alberto da Silva and FARIA, Gláucia Amorim. Optimal size of plots for experiments with papaya plants under greenhouse conditions. Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp. 1411-1415. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542007000500021.
This work hap the adm was of determining the optimal size of plots of papaya plants in greenhouse experiments. Two uniformity essays with the cultivars Golden, from the Solo group, and the Tainung Nº 1, from the Formosa group, were conducted. The essays were formed by plants in polyethylene plastic bags, placed in 10 lines with 10 plants in each line. Between the cutting period until the appearance of the first functional flower, evaluations of the variables were performed: plant height, stem diameter, number of leaves and length and width of the mature leaf. Several sizes and plot forms, in which each plant was considered atfirt as a basic unit. Were simulated till fifty plants for basic unity. For the estimation of the optimal size of plots, one applied the methods of maximum modified curvature. One may conclude that, for the materials and variables studied, the optimal plot size may be formed by eight plants.
