We analyze the one loop corrections to hadronic Z decays in an R-parityviolating extension to the Minimal Supersymmetric Standard Model (MSSM).Performing a global fit to all the hadronic observables at the Z-peak, weobtain stringent constraints on the R-violating couplings constants lambda' andlambda''. As a result of the strong constraints from the b asymmetry parametersA_b and A_FB(b), we find that the couplings lambda'{i31}, lambda'{i32}, andlambda''{321} are ruled out at the 1 sigma level, and that lambda'{i33} andlambda''{33i} are ruled out at the 2 sigma level. We also obtain Bayesianconfidence limits for the R-violating couplings.Comment: 30 pages, 19 postscript figures, REVTeX, new section 8 on Bayesian  confidence limits adde
