The Dirac field is studied in a Lyra space-time background by means of the
classical Schwinger Variational Principle. We obtain the equations of motion,
establish the conservation laws, and get a scale relation relating the
energy-momentum and spin tensors. Such scale relation is an intrinsic property
for matter fields in Lyra background.
