In supergravity theories with a very light gravitino, the gluino decays
dominantly to a gluon and a gravitino. This results in a much larger missing
$E_T$ for the multijet final states in hadronic colliders. We use the latest
Tevatron data for the multijet final states to set a new absolute lower bound
of 3.0 x 10^{-13} GeV for the light gravitino mass.
