We study the production of mesons in nucleon-nucleon reactions at center-of-mass energies of a few GeV using an N_f=2 linear sigma model, extended by including the N_f= 2 multiplets of (pseudo-) scalar and (axial-) vector mesons and a doublet of the nucleon together with its chiral partner (the N^*(1535) or N^*(1650) resonance). Results of the calculations are compared to experimental data.
