  We consider the Schwinger production of baryons in an external electric field
in the worldline instanton approach. The process occurs in the confinement
regime hence the holographic QCD and the Chiral Lagrangian are used as the
tools. The new exponentially suppressed processes in a constant electric field
involving the composite worldline instantons are suggested. These include the
non-perturbative decay of a neutron into a proton and charged meson and the
spontaneous production of $p\bar{n}\pi^{-}$ and $n\bar{p}\pi^{+}$ states.
