  We study pair production from a strong electric field in boost-invariant
coordinates as a simple model for the central rapidity region of a heavy-ion
collision. We derive and solve the renormalized equations for the time
evolution of the mean electric field and current of the produced particles,
when the field is taken to be a function only of the fluid proper time $\tau =
\sqrt{t^2-z^2}$. We find that a relativistic transport theory with a Schwinger
source term modified to take Pauli blocking (or Bose enhancement) into account
gives a good description of the numerical solution to the field equations. We
also compute the renormalized energy-momentum tensor of the produced particles
and compare the effective pressure, energy and entropy density to that expected
from hydrodynamic models of energy and momentum flow of the plasma.
