  We investigate OZI rule violation in omega and phi-meson photoproduction off
nucleons. Data on the total cross sections indicate a large phi/omega ratio of
about 0.8 at the maximal available photon energy that is in good agreement with
expectations from QCD. On the other hand, data at large four momentum transfer
exhibit a ratio of about 0.07, showing that the perturbative QCD regime is not
approached at |t| > 2 GeV^2 and photon energies E_\gamma < 4 GeV. The
anomanously large phi/omega ratio at low energies, that is close to the
reaction threshold, remains to be explained within nonperturbative QCD.
