  Associated production of a Higgs boson with a heavy, i.e. top or bottom,
quark-anti-quark pair provide observation channels for Higgs bosons at the LHC
which can be used to measure the respective Yukawa couplings. For the light
supersymmetric Higgs boson we present SUSY-QCD corrections at the one-loop
level, which constitute a significant contribution to the cross section.
