| Sumario: | The production of quality seedlings is influenced by several factors, the substrate being one of the most important for fruit species. Thus, the objective of this study was to evaluate and select alternative substrates for the production of yellow passion fruit seedlings in Roraima. The work was carried out in Boa Vista at the Federal University of Roraima. The substrates used were: Soil, commercial compound OrganoAmazon®, vermicompost PuroHumus®, carbonized rice husk, fresh rice husk and sawdust. The experimental design used was completely randomized, in a 2 × 18 factorial scheme, with two cultivars of yellow passion fruit (Golden Star and Imperial) and eighteen substrates made using mixtures. The variables analyzed after 60 days were: shoot height (H), stem diameter (DC), root length (CR), number of leaves (NF), total dry matter (MST), shoot dry matter (MSA), root dry matter (MSR) and seedling quality index. The substrates made with 50% PuroHumus® + 50% Soil (S5) and 25% OrganoAmazon® + 25% PuroHumus® + 50% Soil (S12) favor obtaining higher quality seedlings in the Golden Star cultivar. The substrates formulated with 25% PuroHumus® + 25% sawdust + 50% Soil (S18), 50% PuroHumus® + 50% Soil (S5) and 25% OrganoAmazon® + 25% PuroHumus® + 50% Soil (S12) are indicated for the production of seedlings of the Imperial cultivar. The use of pure soil or in mixture with rice husks (carbonized or in natura), sawdust or OrganoAmazon® is not indicated for the production of yellow passion fruit seedlings. |
