Similarity variables are used to transform the non-linear governing equations are reduced to ordinary partial differential equations, solved by shooting process with BVP4C. Results for velocity, temperature and concentration fields for different physical parameters have been presented in detail with graphical representation.

INTRODUCTION In recent years, the importance of MHD boundary layer Casson fluid flows in industrial areas like plasma, MHD power generator, chemical engineering and electronics, stellar and planetary magnetospheres, aeronautical plasma flows. The study of porous material on heat and mass transfer is very important in the areas of filtration, chemical engineering, crop damage because of freezing, pollution of environmental and humidity on agriculture and fruit tree groves. We have to extend the research paper of [2] and [3] to examine the MHD flow over moving vertical plate through porous medium. In view of such applications, several authors [4] to [10] studied the problems of MHD fluid flow with heat transfer. Also, the MHD Casson fluid flow through porous medium problem has been studied by several authors [11] to [33]. The novelty of the study is consideration of boundary layer MHD Casson flow of an electrically conducting fluid through porous medium with hear source, radiation.
