By means of quark potential model and Warke approximation, and introducing as compensation intermediate potential (-1)T+JKre(-r/a2) in the phenomenological one gluon exchange quark interaction potential, the pion-nucleon interaction potential is calculated. The phase shifts of p-N scattering in the six channels S11, S31, P11, P31, P13, P33 are determined for the incident pion kinetic energy in the laboratory coordinate system up to 700 MeV. These results are compared with the experimentally determined phase shifts.
