We compare the predictions of the collinear parton model and the kₜ-factorization approach in JΨand D⋆ meson photoproduction at HERA energies. It is shown that obtained in the both approaches D⋆ meson spectra over pₜ and ηas well as JΨmeson pₜ- and z-spectra are very different. The predictions obtained in the kₜ-factorization approach are agree with the experimental data well. We also predict the nontrivial pₜ-dependence of the the spin parameter α(pₜ) in the JΨphotoproduction.
