Abstract: 
The aim of this study was to evaluate the influence of different formulations of slow-release and conventional fertilizer in Schinus molle seedlings production. The experiment was conducted at São Paulo State University, School of Engineering, municipality of Ilha Solteira, Brazil, in a Pad & Fan greenhouse type (Average Temp. 26 °C and 55% RH). The seedlings were grown in the same cited environment in polyethylene trays filled with commercial substrate. When seedlings presented 3-4 leaves, 30 days after sowing they were transplanted to 4 L plastic bags, with the following treatments: T1 = Control, T2 = Osmocote® 3M (14-14-14), T3 = Basacote® 3M (15-09-12) and T4 = TecNutri® conventional fertilizer (05-13-13). Mixture of soil + commercial substrate (1:1) formed the substrate and fertilizer at a dosage of 3 g L-1 was used. The experimental design was completely randomized with 4 treatments and 06 replications and evaluations were performed 55 days after planting. The following characteristics were analysed: plant height, stem diameter (mm), plant height and stem diameter ratio and number of leaves. For 55 days seedlings the best treatment was the conventional fertilizer TecNutri®
