Emergence parameters were evaluated for seedling development and yield of fruits of three tomato cultivars (Pêra Amarela, Pêra Vermelha and Carolina) under protected environments and different substrates. A greenhouse and a nursery with 50% monofilament shading were used. In these environments, the following substrates were tested: 50% cassava foliage (F) + 50% Vida Verde(r) (V), 50% cassava foliage + 50% cattle manure (C), 50% cassava foliage + 50% poultry manure (P), 25% cassava foliage + 25% Vida Verde(r) + 25% poultry manure + 25% cattle manure for the three evaluated cultivars. The best seedlings were grown in the F+C and F+V+C+P substrates, reaching the quality index of 0.0069. Both environments are indicated for the formation of seedlings with the use of the F+V+C+P mixture, producing seedlings weighing 0.0463 g of dry mass. Cultivar Carolina presented growth parameters and vigor, being the best cultivar, with a diameter and height ratio of 2.38. The same substrates that formed the best seedlings also promoted higher fruit yield per plant, with an average of 23.11 g/fruit and diameter of 20.64 mm. The best environment for fruit production was the nursery with F+C and F+V+C+P substrates. Substrates containing 50% poultry manure or 50% Vida Verde(r) are not recommended
