We have constructed five-dimensional plane-symmetric cosmological models in
the presence of massive scalar field in Lyra manifold when the source of the
gravitational field is a massive string with r = (1+w)l
(Takabayasi string). The role of massive scalar field in the evolution of the
universe has been studied. The physical and kinematical behavior of the models
is discussed.
