| description | Inflorescence brassicas, such as broccoli and cauliflower, rich in fiber and vitamins, are widely consumed in Brazil, and present an average production of 23 t ha-1. Despite this demand, the quality of seedlings of both species is one of the main factors that limit production. Thus, the objective of this study was to evaluate broccoli and cauliflower seedling emergence and production in different substrates, using the irrigation method named Deep Film Technique (DFT) on a table. The experiment was carried out in a completely randomized design, 7×2: substrate compositions (volumetric proportions of 1:0:0; 0:1:0; 0:0:1; 1:1:1; 1:1:0; 1:0:1 and 0:1:1, containing commercial substrate Carolina Soil®, carbonized rice husk and medium textured sand) and inflorescence brassicas (broccoli and cauliflower), with four replications. Each experimental unit consisted of 50 seeds/seedlings. At 21 days after sowing (DAS), it was evaluated the percentage, index, time, speed and frequency of emergence, and, at 35 DAS, clod stability, number of leaves and seedling length. It was observed that there was good seed germination and seedling formation for both species in all substrate compositions and with the aid of the DFT irrigation method on a table. Under these conditions, for both species, substrate compositions of 1:0:0; 1:1:1 and 1:1:0 are recommended. |

Las brasicáceas de inflorescencia, como el brócoli y la coliflor, ricas en fibra y vitaminas, son ampliamente consumidas en Brasil, resultando en una producción promedio de 23 t ha-1. A pesar de esta demanda, la calidad de las plántulas de ambas especies es uno de los principales factores que limitan la producción. Así, el objetivo de este trabajo fue evaluar la emergencia y producción de plántulas de brócoli y coliflor en diferentes sustratos, utilizando el método de riego denominado Deep Film Technique (DFT) en mesa. El experimento se llevó a cabo en un diseño completamente al azar, 7×2: composiciones de sustrato (proporciones volumétricas de 1:0:0; 0:1:0; 0:0:1; 1:1:1; 1:1:0; 1:0:1 y 0:1:1, con sustrato comercial Carolina Soil®, cascarilla de arroz carbonizada y arena de textura media) y brásicas de inflorescencia (brocoli y coliflor), con cuatro repeticiones. Cada unidad experimental conto de 50 semillas/plántulas. A los 21 días después de la siembra (DDS), se evaluó porcentaje, índice, tiempo, velocidad y frecuencia de emergencia a los 35 DDS, y estabilidad del terrón, número de hojas y longitud de las plántulas. Se observó que hubo buena germinación de semillas y formación de plántulas para ambas especies en todas las composiciones de sustrato y con la ayuda del método de riego DFT en mesa. En estas condiciones para ambas especies evaluadas, las composiciones de sustrato 1:0:0; 1:1:1 y 1:1:0 son las recomiendadas.
