  We discuss gravitino production from reheating in models where the splitting
between particle and sparticle masses can be larger than TeV, as naturally
arising in the context of split supersymmetry. We show that such a production
typically dominates over thermal contributions arising from the interactions of
gauginos, squarks and sleptons. We constrain the supersymmetry breaking scale
of the relevant sector for a given reheat temperature. However the situation
changes when the gravitinos dominate the Universe and decay before
nucleosynthesis. We briefly describe prospects for a successful baryogenesis
and a viable neutralino dark matter in this case.
