We have investigated spatially homogeneous anisotropic Bianchi type-II, VIII & IX cosmological models in the presence of pressure less matter and modified holographic Ricci dark energy in the frame work of f(R, T) gravity in the context of late time accelerating expansion of the universe. The solutions of the field equations obtained using (i) a relation between metric potentials and (ii) the modified holographic Ricci dark energy. We have determined the cosmological parameters, namely, EoS parameter, matter energy density, anisotropic dark energy density, deceleration parameter. We discuss some physical and geometrical properties of the obtained models which are found to be consistent with recent observation
