Query: Hadroproduction of var(phi)-mesons in the Quark-Gluon String model   We consider the experimental data on var(phi)-meson production in
hadron-nucleon collisions for a wide energy region. The Quark-Gluon String
Model quantitatively describes the spectra of secondary var(phi), as well as
the ratios of var(phi)/pi^- and var(phi)/K^- production cross sections.
