Sumario: The objective of this study was to evaluate the association of three species of oleaginous: Jatropha curcas (Linn), Ricinus communis (Linn) and Moringa oleifera (Lam) in the establishment phase. The study was conducted in the experimental area of Colegio Postgraduados, Campus Veracruz, in Mexico from 2013 to 2014. A completely randomized design was used and ten plants of each species were randomly sampled; plant height, stem and the primary branch diameter, the projection of the crown and pests and diseases problems were evaluated. Descriptive statistics (average) was used. Jatropha and Moringa had a growth spurt (20 cm) between 45 and 60 days of evaluation, while Ricinus growth was slower (10 cm) and its height was lower than reported in the literature. The variables of the stem and the primary branch diameter as well as the crown projection of J. curcas and M. oleifera had little variability; Ricinus plants were affected by pests and pathogens; however, the insects found were not the same in the species tested. Moringa was the species that had the highest value in most of the variables evaluated and Jatropha had a morphological pattern similar to that found in monoculture systems. For Ricinus, the association was not favourable due to the effect of shade and the severe attack of pathogens.
