Abstract
We investigate the meson, baryon and anti-baryon productions in 
and Kp collisions in terms of a constituent cascade model which
includes charm flavour. The constituent diquark in an incident baryon
has a tendency to get a large momentum fraction, resulting in
considerable difference of subenergies for particle productions from
quark-diquark and quark-antiquark chains in a meson-baryon
collision. As a consequence, the leading particle effects on D
meson productions are expected to be quite different in 
and
beams at present accelerator energies.
