  We present a comparative study of the pion induced production of $K^0
\Lambda$ and $D^- \Lambda_c^+$ off the nucleon. A hybrid framework is utilized
by combining an effective Lagrangian method with a Regge approach. We consider
the $t$-channel process in a plannar diagram by vector-meson Reggeon exchanges
and the $u$-channel one in a non-planar diagram by baryon Reggeon exchanges.
The present model reproduces the $K^0 \Lambda$ production data well with a few
parameters. Having fixed them, we predict the $D^- \Lambda_c^+$ production,
which turns out to be about $10^4-10^6$ times smaller than the strangeness one,
depending on the kinematical regions.
