dc.description.abstract Organic variety trials were conducted in 2010 and 2011 to evaluate 14 tomato (Solanum lycopersicum L.) cultivars at Lajas, Puerto Rico. Significant differences in marketable fruit yield were observed among cultivars in both years. In 2010, yields ranged from 72.1 t/ha for ‘Roma’ to 8.6 t/ha for ‘Marion’, with an overall mean of 36.4 t/ha. ‘Roma’, ‘Neptune’ (56.8 t/ha), and ‘BHN 444’ (56.2 t/ha) had the highest yields in 2010. In 2011, yields ranged from 46.1 t/ha for ‘Flora Dade’ to 8.7 t/ha for ‘Roma’, with an overall mean of 27.8 t/ha. ‘Flora Dade’, ‘BHN 444’ (43.5 t/ha), and ‘Celebrity’ (38.3 t/ha) had the highest yields in 2011. Open pollinated cultivars performed with more variability between the two seasons than the hybrid controls. This study indicates that tomato can be grown successfully in the tropics under an organic management system using either open pollinated cultivars or hybrids.
dc.description.abstract Se llevaron a cabo pruebas de variedades en Lajas, Puerto Rico en 2010 y 2011 para evaluar 14 cultivares de tomate (Solanum lycopersicum L.) con manejo orgánico. Se observaron diferencias significativas entre cultivares para el rendimiento comercial de frutas para los dos años. En el 2010, el rango de rendimiento fue entre 72.1 t/ha para ‘Roma’ a 8.6 t/ha para ‘Marion’, con un promedio general de 36.4 t/ha. ‘Roma’, ‘Neptune’ (56.8 t/ha) y ‘BHN 444’ (56.2 t/ha) tuvieron los rendimientos más altos en el 2010. En el 2011, hubo un rango en el rendimiento de 46.1 t/ha para ‘Flora Dade’ a 8.7 t/ha para ‘Roma, con un promedio general de 27.8 t/ha’. ‘Flora Dade’, ‘BHN 444’ (43.5 t/ha) y ‘Celebrity’ (38.3 t/ha) tuvieron los rendimientos más altos en el 2011. Los cultivares de polinización abierta presentaron mayor variabilidad entre años que los testigos híbridos. Este estudio indica que se puede cultivar el tomate exitosamente bajo un sistema de manejo orgánico en el trópico usando cultivares de polinización abierta o híbridos.
