Depending on their masses, supersymmetric particles can affect various
measurements in Z decay. Among these are the total width (or conseque
nt extracted value of alpha(s)), enhancement or suppression of various
flavors, and left-right and forward-backward asymmetries. The latter
depend on squark mass splittings and are, therefore, a possible test o
f the supergravity related predictions. We calculate leading order cor
rections for these quantities considering in particular the case of li
ght photino and gluino where the SUSY effects are enhanced. In this li
mit the effect on alpha(s) is appreciable, the effect on R-b is small,
and the effect on the asymmetries is extremely small.
