  By duality approach, we study condensate mass of QCD vacuum via dilaton wall
background in presence of parameter $c$ which represents the gluon condensation
in holographic set up. First from Wilson line calculation we find $m^2_0$
(condensate parameter in mixed nonlocal condensation) whose behavior mimics
that of QCD. The value of $m^2_0$ that we find by this approach, is in
agreement with QCD data. In the second step we consider produced mass m via
Schwinger effect mechanism in presence of parameter $c$. We show that generally
gluon condensation contribute mass dominantly and produced mass via Schwinger
effect is suppressed by $m_0$ .
