Abstract
We evaluate the supersymmetric QCD corrections to single top quark production via $q{q}^{\ensuremath{'}}\ensuremath{\rightarrow}t\overline{b}$ at the Fermilab Tevatron in the minimal supersymmetric model. We find that within the allowed range of squark and gluino masses the supersymmetric QCD corrections can enhance the cross section by a few percent. The combined effects of SUSY QCD, SUSY EW, and the Yukawa couplings can exceed 10% for the smallest allowed $\mathrm{tan}\ensuremath{\beta}(\ensuremath{\simeq}0.25)$ but are only a few percent for $\mathrm{tan}\ensuremath{\beta}>1.$
