%X Con el objetivo de estudiar el efecto del EcoMic  en la emergencia de las pl¨¢ntulas de Jatropha curcas, se hizo una prueba de observaci¨®n en el laboratorio de an¨¢lisis qu¨ªmico de la Estaci¨®n Experimental de Pastos y Forrajes  Indio Hatuey . Se usaron semillas reci¨¦n cosechadas, en dos tratamientos: semillas inoculadas con EcoMic  (T1), y sin in¨®culo (T2), con cuatro r¨¦plicas de 100 semillas cada una. Se utiliz¨® un dise o totalmente aleatorizado y se realizaron 15 observaciones (a los 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 y 16 d¨ªas de emergencia). Las medias se compararon a trav¨¦s de un an¨¢lisis descriptivo. El efecto del T1 fue notable durante todo el per¨ªodo; a partir del cuarto d¨ªa se observaron 45 pl¨¢ntulas emergidas, lo que represent¨® el 11,2% del total de las tratadas con este biofertilizante, y el ¨²ltimo d¨ªa del estudio hab¨ªa emergido el 96,2%. En el T2 no se observaron pl¨¢ntulas emergidas en ning¨²n momento. Se concluye que el EcoMic  ejerci¨® un efecto positivo en la emergencia de las pl¨¢ntulas de J. curcas al ser utilizado como in¨®culo en condiciones de laboratorio. Se recomienda realizar estudios pregerminativos para determinar la dormancia en la semilla de Jatropha, teniendo en cuenta el empleo del EcoMic  como uno de los tratamientos. In order to study the effect of EcoMic  on the emergence of Jatropha curcas seedlings, an observation test was conducted in the laboratory of chemical analysis of the Experimental Station of Pastures and Forages  Indio Hatuey . Newly-harvested seeds were used, in two treatments: seeds inoculated with EcoMic  (T1), and without inoculation (T2), with four replications of 100 seeds each. A completely randomized design was used and 15 observations were made (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 and 16 days after emergence). The means were compared through a descriptive analysis. The effect of T1 was remarkable throughout the period; since the fourth day 45 emerged seedlings were observed, which represented 11,2% of the total seedlings treated with this biofertilizer, and the last day of the study 96,2% had emerged. In T2 no emerged seedlings were observed at any moment. EcoMic  was concluded to exert a positive effect on the emergence of J. curcas seedlings when used as inoculum under laboratory conditions. To conduct pregerminative treatments is recommended in order to determine dormancy in Jatropha seeds, taking into consideration the use of EcoMic  as one of the treatments.
