In the framework of perturbative QCD and nonrelativistic bound state formalism, we calculate the production of J/{psi} mesons associated with open-charm particles at HERA and Tevatron conditions. We show that the contribution from J/{psi}+c+c channel becomes comparable with that of J/{psi} sole production at high J/{psi} transverse momenta (approximately, at p{sub {psi},T}>10 GeV). We investigate the J/{psi} polarization effects and kinematic correlations between J/{psi} mesons and the accompanying open-charmed mesons. We show that the correlations are sensitive to the initial k{sub t} of the colliding partons, and so, can be considered as an additional test discriminating the collinear parton model and the k{sub t}-factorization approach.
