  The inclusive distributions of gluons and pions for high-energy NN collisions
are calculated. The results for several unintegrated gluon distributions
(UGD's) from the literature are compared. We find huge differences in both
rapidity and $p_t$ of gluons and $\pi$'s in NN collisions for different models
of UGD's. The Karzeev-Levin UGD gives good description of momentum distribution
of charged hadrons at midrapidities. We find that the gluonic mechanism
discussed does not describe the inclusive spectra of charged particles in the
fragmentation region.
