Numerical investigation is performed to study the two dimensional flow with heat and mass transfer of a viscous, incompressible, electrically conducting and radiating fluid over a nonlinear porous stretching surface with partial slip effects in the presence ofnon-uniform heat source/sink. Using similarity transformations, the governing partial differential equations are transformed into a system of nonlinear ordinary differential equations and are solved numerically using Nachtsheim Swigert shooting iteration technique together with fourth order Runge-Kutta algorithm. The effects of physical parameters on the velocity, temperature and concentration distributions are depicted graphically. It has been found that the effect of slip parameter is to decrease the velocity for its increasingvalues and the thermal boundary layer thickness increases for increasing values of temperature ratio parameter and non-uniform  heat source/sink parameter. A comparative study between the existing results and the present study is carried out and the results are found to be in excellent agreement. The values of skin-friction coefficient, Nusselt number and Sherwood number for different physical parameters are tabulated and discussed.
