Abstract

Ornamental plants require a substrate that ensures the germination and healthy growth and vigor of the seedlings. Thus, this study aimed at studying the most suitable substrate for the production of zinnia seedlings from waste wood. The substrates evaluated in greenhouse were: Plantmax®; Sawdust (SM); SM + clay soil + sand (1: 2: 1); SM + clay soil + sand (2: 2: 1); SM + clay soil + sand (2: 1: 1); SM + clay soil (1: 1); SM + clay soil (1: 1) + Simple Superphosphate (SS); SM + clay soil (1: 1) + Sulphate Ammonium (SA); SM + clay soil (1: 1) SA + + SS; SM + SS; SM + SA; and SM + SS + SA. The sawdust in proportions 1: 1 (sawdust / clay soil) behaved like an excellent ingredient composition on the substrate to produce seedlings zinnia. The SM + SS provides higher percentages of plant emergence, reaching a rate 30% higher compared to the Plantmax®. The superphosphate associated with ammonium sulfate promoted increment in height of zinnias seedlings. The sawdust associated with superphosphate and ammonium sulfate provide excellent results in substrate composition for plant emergence and establishment of seedlings zinnias.

Key words: Ornamentals, propagation, sawdust.
