  The brane cosmology has invoked new challenges to the usual Big Bang
cosmology. In this paper we present a brief account on thermal history of the
post-inflationary brane cosmology. We have realized that it is not obvious that
the post-inflationary brane cosmology would always deviate from the standard
Big Bang cosmology. However, if it deviates some stringent conditions on the
brane tension are to be satisfied. In this regard we study various implications
on gravitino production and its abundance. We discuss Affleck-Dine mechanism
for baryogenesis and make some comments on moduli and dilaton problems in this
context.
