Realistic N=1 supergravity theories with a gravitino mass of order 1 TeV require a period of inflation to dilute the gravitino abundance. Moreover, if the gravitino is unstable the reheat temperature is bounded to be no greater than O(108 GeV). We show that such models may still have acceptable rates of baryosynthesis and discuss possible mechanisms.
