Resumo:  ABSTRACT Papaya is characterized as one of the most important crops in Brazil. Thus, good quality seedlings are essential for formation of orchards in agricultural production. This study aimed to evaluate shading levels and substrate compositions for production of papaya seedlings. Growing environments were evaluated with 0, 18, 35, and 50% shading and substrates from combinations (%) of hillside soil (HS), cattle manure (CM), Bioplant® (BP), washed fine sand (FS), and super fine-grained vermiculite (FV). As there was no replication for the growing environments, the group of experiments were analyzed using a 4 × 4 factorial arrangement (4 shades × 4 substrates), with five replications. Growth and biometric relationships were analyzed. Substrates consisting of 30% HS + 15% CM + 20% BP + 20% FS + 15% FV and 45% HS + 0% CM + 20% BP + 20% FS + 15% FV, as well as environments with 18 and 35% shading formed seedlings with higher plant heights, diameters, phytomass, and Dickson quality indices. The results showed that substrates with a higher content of hillside soil and lower content of cattle manure, associated with an environment with 18 or 35% shading, provided high-quality seedlings.
