The seedling transplanting ages is a factor of great importance because it can affect the quality and yield of plants if the volume of the cell is not compatible with the phenology of seedlings at time of transplantation. The experiment was conducted at São Manuel Experimental farm, Faculdade de Ciências Agronômicas da UNESP, from March to August, 2009. The objective of this study was to evaluate the effect of seedling age on cabbage production, hybrid Kenzan. The seedlings were grown in polystyrene trays containing 128 cells. Seedings were done every four days and contained the following treatments: 37, 41, 45, 49 and 53 days after sowing (DAS). The experimental design was randomized blocks, with five replications. On transplantation’s day (11/05/2009), the number of leaves, fresh and dry weight and height, were evaluated to the characterization of seedlings. It was observed that the seedling age had no influence on traits at harvest: number of leaves inside and outside of “head”, fresh weight of shoot and “head”, dry mass of shoot and “head” and length of “heart”.
