Intercropping maize cultivation and the legume species use as a fertilization method is a quite common procedure used by brazilian Northeastern farmer. Thus, this work had as an objective to evaluate maize seeds physiological quality (Zea mays L.), cv. BR-106, produced in isolated and intercropped culture systems (maize, maize + guandu bean and maize + faba bean in the absence and presence of chemical fertilizer and velvet bean. The essay was lead at the Seeds Analysis Laboratory of Paraíba Federal University - Campus II, Areia - PB. Independently of the culture systems, mineral fertilizer and velvet bean, germination, seedlings emergency in sand and the emergency speed index were high. From the results, it is observed that the mineral fertilizer favored maize seeds viability and vigor; velvet bean, besides not having competed with the culture systems, favored the physiological quality of maize seeds coming from intercropping and the intercropping maize + guandu bean favored the vigor the seed maize.
