We study a strong suppression of the relative production rate (d-Au)/(p-p) for inclusive high-p{sub T} hadrons of different species at large forward rapidities (large Feynman x{sub F}). The model predictions calculated in the light-cone dipole approach are in a good agreement with the recent measurements by the BRAHMS and STAR Collaborations at the BNL Relativistic Heavy Ion Collider. We predict a similar suppression at large p{sub T} and large x{sub F} also at lower energies, where no effect of coherence is possible. This allows us to exclude the saturation models or the models based on Color Glass Condensate from interpretation of nuclear effects.
