  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, however, that the gluonic
mechanism discussed does not describe the inclusive distributions of charged
particles in the fragmentation region. Some of the missing mechanisms are
calculated with the help of unintegrated parton distributions being solutions
of the Kwieci\'nski CCFM equations. We predict an asymmetry in $\pi^+$ and
$\pi^-$ production which could be studied by the BRAHMS collaboration at RHIC.
