We examine the processes {ital p{bar p}}{r arrow}{ital {tilde g}{tilde g}}, {ital {tilde q}{tilde g}}, and {ital {tilde q}{tilde q}} at Fermilab Tevatron collider energies and find an observable signal for {ital Z}{sup 0}+{ge}2 jets+missing {ital p}{sub {ital T}} events due to cascade and loop decays of squarks and gluinos. This signal occurs in a substantial region of the supersymmetric parameter space provided only that the Higgsino-mixing mass parameter is small. We evaluate several different standard-model backgrounds, and show that the signal (which can yield up to 25 events in the next Tevatron run) exceeds background for {ital m}{sub {ital {tilde q}}} or {ital m}{sub {ital {tilde g}}} as large as 200 GeV. Distributions which discriminate the supersymmetric signal from background are also shown.
