  In this paper, we study the slowly rotating neutron stars in $f(R, T)$
gravity based on Hartle-Thorne formalism. We compute the mass, radius, moment
of inertia, change in radius and binding energy due to rotation, eccentricity,
quadrupole moment and the tidal love number. The quantities, which are of the
second order in angular velocity, like, change in radius and binding energy due
to rotation, eccentricity and quadrupole moment, deviate more from their
corresponding general relativistic counterparts in lighter neutron stars than
heavier ones. Whereas the moment of inertia, which is of the first order in
angular velocity, in $f(R, T)$ gravity, slightly diverges from the general
relativistic one. The Equation of state-independent I-Love-Q relation retains
in $f(R, T) $ gravity, and it coincides with the general relativistic ones
within less than one percent even for the maximum allowed coupling parameters.
