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 Fermilab Tevatron data for the multijet final states to set a new absolute lower bound of $3.0\times {10}^{-13}\mathrm{GeV}$ for the light gravitino mass.
