PRODUCTION OF TOMATO SEEDLINGS USING DIFFERENT SUBSTRATES AND TRAYS IN THREE PROTECTED ENVIRONMENTS

摘要

abstract_textpThe seedlings production is an essential part for vegetables production. Thus, this study aimed to evaluate the environment, the substrates and the containers in the development of tomato seedlings, cv. Santa crus Kada Gigante, in Aquidauana -MS, Brazil region, from October to November, 2008. Polystyrene trays with 72; 128 and 200 cells, filled with four substrates (soil; Plantmax (R) coconut fiber and vermiculite) were tested in three protected environments (greenhouse; screened with Sombrite (R) and screened with Aluminet (R)). The experimental design was completely randomized, factorial scheme 3x4 (three trays x four substrates), with four replications, being analyzed individual variance analysis and joint analysis for the environments. The environment with screens (Sombrite (R) and Aluminet (R)), the trays with 72 cells and the vermiculite produced better results./p/abstract_text
