  The "square root" of the Dirac operator derived on the superspace is used to
construct supersymmetric field equations. In addition to the recently found
solution - a vector supermultiplet I demonstrate how a chiral supermultiplet
follows as the solution. Both vector and chiral supermultiplets are shown to
obey appropriate (massless) equations of motion. This procedure yields thus a
complete set of fields and their equations necessary to construct
renormalizable supersymmetric theories. The problem of masses and interaction
is also discussed.
