A detailed analysis of the processes of the type NN -> Dπis presented taking into account the exchange graphs of a nucleon and a pion. A large sensitivity of polarization observables to the off-mass shell effects of nucleons inside the deuteron is shown. The influence of the inclusion of the P-wave in the Deuteron Wave Function (DWF) is studied. We have analysed the sensitivity of all the observables to the form of πNN - current taking into account the off-shellnis of the nucleon and the choice of the DWF relativistic form. One can see the very large sensitivity of all the observables, especialy of the polarization characteristics to the choice of the DWF form. The inclusion of the P-wave contribution to the DWF within framework of Gross's approach results in a better description of the experimental data on the differential cross section and the polarization observables.
