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.
