MODOLO, Valéria A.; TESSARIOLI NETO, João  e  ORTIGOZZA, Luís Enrique R.. Influence of different tray cell sizes and substrates on the production of okra plantlets and fruits. Hortic. Bras. [online]. 2001, vol.19, n.1, pp.39-42. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362001000100008.

This study proposed to evaluate the production of okra fields established by using seedling transplant. The experiment was carried out in a greenhouse at the Escola Superior de Agricultura "Luiz de Queiroz" in São Paulo, Brazil. Trays with different cell size were used in the okra seedling production. The substrates used were a blend of a commercial mixture (Gioplanta). A completely randomized block design, with 3 x 4 factorial arrangement (3 types of trays and 4 different substrates) was used, in a total of 12 treatments. In the field 30 seedlings per each treatment were transplanted using 1,0 m between rows and 0,5 m within each plant in the row. Each plot was constituted by 5 rows of 3,0 m and area of 15 m2. Commercial fruits size (8 - 10 cm length) were harvested from the 12 central plants 49 days after seedling transplanting. Number and fruit weight were evaluated. In the field the plants grown in largest cell volume produced more fruits than plants from small cell volume, regardless of the substrate. The lowest yield was obtained when GII and carbonized rice hulls were mixed (1:1) in the seedling production, independently of the tray type used.
