Abstract: (Springer)

In this paper, we have studied the Einstein-Rosen space time in

f(R,T)

gravity by considering the second model of Harko et al. (Phys. Rev. D 84:024020, 2011),

f(R,T) = f_{1}(R)+f_{2}(T)

, where

f_{1}(R)=\lambda R

,

f_{2}(T)=\lambda T

and

f_{1}(R)=\lambda R

,

f_{2}(T)=\lambda T^{2}

. The matter field is considered in the form of perfect fluid. It is observed that, the perfect fluid represent the Zel’dovich universe in both the forms.
