  We consider the photoproduction of secondary mesons in the framework of the
Quark-Gluon String model. At relatively low energies, not only cylindrical, but
also planar diagrams have to be accounted for. To estimate the significant
contribution of planar diagrams in gamma-p collisions at rather low energies,
we have used the expression obtained from the corresponding phenomenological
expression for pi-p collisions. The results obtained by the model are compared
to the existing SLAC experimental data. The model predictions for light meson
production at HERMES energies are also presented.
