  The process of baryon number transfer due to string junction propagation in
rapidity space is considered. It leads to a significant effect in the net
baryon production in pA collisions at mid-rapidities and an even more
significant effect in the forward hemisphere for the cases of \pi A
interactions. The results of numerical calculations in the framework of the
Quark-Gluon String Model are in reasonable agreement with the data. Special
consideration is given to \Lambda produced in {\pi^-}-A collisions extracted
from data of WA89 Collaboration.
