An experiment with three types of trays with four substrates was carried out in a greenhouse using trays with different cell sizes for okra seedling production. The substrates used were a blend of a commercial mixture made by Empresa Gioplanta. The experimental design consisted of completely randomized blocks, in a 3 x 4 factorial arrangement, with 3 types of trays and the 4 substrates. The evaluation of growth was done 32 days after germination. The results indicated that the production of okra seedlings in trays with the largest cell volume presented the best results for all the parameters studied. Trays of various types that contained substrate GII and carbonized rice hulls in the proportion 1:1, presented the least developed seedlings. Fertilization applied initially and during seedling growth permitted a better development of okra seedlings.
