The contribution of color-octet heavy quarkonium production mechanism in P+ Fe → J/ψ + γ + X process is calculated and discussed. The results show that color-octet contributions are rather large and sometimes can exceed the color-singlct contributions. Using the structure function of Fe given by double Q2-rescaling model, the influence of nuclear effect on this process is also studied.``
