An axially symmetric space-time is considered in the presence of a perfect fluid source in the framework of f (R, T) gravity, where R is the Ricci scalar and T is the trace of the energy-momentum tensor proposed by Harko et al. (Phys. Rev. D 84, 024020, (2011)). We assume the variation law of mean Hubble parameter to obtain the exact solutions of the field equations. The geometrical and physical parameters for both the models are studied.
