A study was conducted at the Pasture and Forage Research Station Indio Hatuey, in order to morphologically characterize eight Moringa oleifera (Lam.) provenances under nursery conditions. A completely randomized design was used. The following indicators were evaluated: germination, emergence, survival, plant height, stem diameter and number of leaves. Five replications of 25 seeds per provenance were used for the germination test (21 days); and 30 bags were planted for each provenance at the nursery. The provenance Holguín-Mayarí had the best performance regarding height (17,55 cm) growth rate (0,43 cm/day), number of leaves (seven) and stem diameter (0,37 cm). Plain, Holguín-Mayarí and Paraguay were the ones with the best emergence and survival (100 %). The lowest values were shown by Guatemala (average height: 14 cm, emergence: 76 %, germination: 49 %). None of the provenances exceeded 85 % of germination. There were no lesions due to the attack by insects or diseases. It is concluded that these provenances have morphological characteristics which differentiate them from each other, and that Holguín-Mayarí showed the best performance in the evaluated indicators. To perform further morphoagronomic studies of the different M. oleifera provenances is recommended.
