    Substrate is one of the fundamental factors in tomato seedling production. The emergence and initial growth of tomato seedlings (Solanum lycopersicum L.) in different substrates was evaluated. The research was carried out at the Maranatha Educational Unit, located in El Carmen, Manabí, Ecuador. Polystyrene culture trays with 50 cells (volume 300 cm3) were used. The seeds used were of the Floradel variety. Three treatments (substrates) were established: agricultural soil (black soil, T1), cocoa harvest residues (cocoa soil, T2) and wood cuttings (sawdust, T3), with three replicates, each with 50 plants, in a totally randomized block treatment design, each tray corresponding to one treatment. The variables evaluated were emergence (%) and seedling height (cm), and in the last sampling, stem diameter (mm) was measured. Seedling emergence averaged 72%. T1 showed 83% emergence and seedling height of 8.13 cm and 2.45 mm stem diameter. It was concluded that the black soil generated the greatest development of the tomato seedlings, presenting the greatest height and diameter, even though they did not have the greatest emergence.

    The substrate is one of the fundamental factors in the production of tomato seedlings. The emergence and initial growth of tomato seedlings (Solanum lycopersicum L.) in different substrates was evaluated. The research was carried out at the Maranatha Educational Unit, located in El Carmen, Manabí, Ecuador. Polystyrene culture trays with 50 cells (volume 300 cm3) were used. The seeds used were of the Floradel variety. Three treatments (substrates) were established: agricultural land (black soil, T1), cocoa harvest remains (cocoa soil, T2) and wood cut remains (sawdust, T3), with three repetitions, each with 50 plants, in a totally randomized block treatment design, each tray corresponded to one treatment. The variables evaluated were emergence (%) and length of the seedlings (cm), and in the last sampling the stem diameter (mm) was measured. Seedling emergence reached an average of 72%. T1 presented 83% of emergence and length of the seedlings of 8.13 cm and 2.45 mm of stem diameter. It is concluded that the black soil generates the greatest development of tomato seedlings, as they present greater length and diameter, even when they did not have the greatest emergence.
