| description | Arugula is known for the spicy flavour of its leaves, and it is an important crop due to its high productivity and multiple harvests per year. However, seedling quality may limit its production. This study examined arugula seedling emergence and production at different sowing densities and substrate compositions. In a greenhouse, the broadleaf cultivar was randomized with a 5×3 factorial design (substrate compositions: 100% medium textured sand (SD), 100% Carolina Soil® commercial substrates (CS), 50%SD+50%CS, 75%SD+25%CS, and 25%SD+75%CS, and sowing densities: 5; 10 and 15 seeds/alveolus); with five replications. Analyzes were carried out on emergence speed index and mean emergence time, as well as on relative frequency, lengths of aerial and root parts, number of leaves, and rating scales according quality for tuft formation (or bouquets) and clod stability. All seeding densities and substrate compositions showed good seedling formation, except for the 100% SD composition, which showed low adherence in the substrate-plant-container-water system for tuft formation and clod stability. Except for 100% SD composition, an average of 70% of seedling emergence was at 9.7 d. For the production of commercial seedlings, it is indicated the use of 10 or more seeds per alveolus, and all substrate compositions tested in this study, except 100% SD. |

La rúcula es conocida por el sabor picante de sus hojas, y es un cultivo importante por su alta productividad y múltiples cosechas al año, sin embargo, la calidad de las plántulas limitan su producción. Este estudio examinó la emergencia y producción de plántulas de rúcula a diferentes densidades de siembra y composiciones de sustrato. En invernadero, el cultivar de hoja ancha se aleatorizó con un factorial 5×3 (composiciones de sustrato: 100% arena de textura media (ATM), 100% sustratos comerciales Carolina Soil® (CS), 50% SD+50 % CS, 75% SD+25% CS, y 25% SD+75% CS; y densidades de siembra de 5, 10 y 15 semillas/alvéolo) con cinco repeticiones. Se realizaron análisis sobre el índice de velocidad de emergencia y el tiempo medio de emergencia, así como sobre la frecuencia relativa, la longitud de las partes aéreas y de la raíz, el número de hojas y las escalas de calificación según la calidad para la formación de penachos (o ramilletes) y la estabilidad del terrón. Todas las densidades de siembra y composiciones de sustrato mostraron buena formación de plántulas, excepto la composición 100% ATM, que mostró baja adherencia en el sistema sustrato-planta-recipiente-agua para la formación de penachos y la estabilidad del terrón. Excepto por la composición 100% ATM, un promedio del 70% de la emergencia de las plántulas fue a los 9,7 d. Para la producción de plántulas comerciales, se indica el uso de 10 o más semillas por alvéolo y todas las composiciones de sustrato probadas en este trabajo, excepto 100% ATM.
