We present a calculation of the D^{*+}, D^+ and D^0 meson single inclusiveproduction cross section for the Tevatron Run II. We use the FONLL approach inperturbative QCD, which, besides including the known next-to-leading ordercorrections, also provides for the resummation at the next-to-leadinglogarithmic level of terms enhanced at large p_T by powers of log(p_T/m), wherem is the charm mass and p_T is its transverse momentum. Non-perturbativeeffects in charm hadronization are extracted, in moment space, from recentALEPH data for D^* fragmentation in e^+e^- collisions.Comment: 11 pages, 5 figures, LaTe
