Top squark contributions to the radiative correction to {ital R}{sub {ital b}} and the top quark decay are analyzed over the relevant MSSM parameter space. One sees a 30{percent} increase in the former along with a similar drop in the latter in going from the Higgsino-dominated to the mixed region. Consequently, one can get a viable SUSY contribution to {ital R}{sub {ital b}} within the constraint of the top quark data only in the mixed region, corresponding to a photino-dominated LSP. We discuss the phenomenological implications of this model for top quark decay and direct top squark production, which can be tested with the Fermilab Tevatron data. {copyright} {ital 1996 The American Physical Society.}
