| Summary: | The production of Passiflora edulis L. seedlings from seeds presents unevenness from emergence to the initial development of the seedlings, with the type of substrate being a factor that can influence this process. This study aimed to evaluate alternative substrates' effect on the emergence and development of yellow passion fruit seedlings. Four types of substrates were assessed: soil + cattle manure + fine sand, Bioplant®, earthworm humus, and Bioplant® + earthworm humus. At 30 days after sowing (DAS), seedling emergence potential and phytotechnical parameters were evaluated. At 70 DAS, survival percentage and phytotechnical parameters were assessed. The substrates influenced the emergence potential and initial development of the seedlings. The use of Bioplant® and earthworm humus substrates resulted in a higher seedling emergence percentage and a greater emergence speed index. Seedling survival percentage was influenced by the type of substrate used, being lower when using the substrate composed of soil + cattle manure + sand. The earthworm humus-based substrate provided more leaves, a longer main root length, and a greater shoot length. To achieve higher emergence potential and better seedling development, the use of earthworm humus-based substrates is recommended.
