Abstract The collective effects on the increase of the K⁺/π⁺ ratio in relativistic heavy-ion collisions are analyzed with the excited nucleon model. The gradual increase of the K⁺/π⁺ ratio from p-Be to p-Au to the Si-Au central collisions may be explained self-consistently by multiscattering and secondary hadron collisions without requiring the formation of the4quark gluon plasma.
