  If extra dimensions are found in the second run of LHC in the $pp$ collisions
at $\sqrt{s}$ = 14 TeV then the string scale can be $\sim$ TeV, and we should
produce string balls at LHC. In this paper we study supersymmetry (squark and
gluino) production from string balls at LHC in $pp$ collisions at $\sqrt{s}$ =
14 TeV and compare that with the parton fusion results using pQCD. We find
significant squark and gluino production from string balls at LHC which is
comparable to parton fusion pQCD results. Hence, in the absence of black hole
production at LHC, an enhancement in supersymmetry production can be a
signature of TeV scale string physics at LHC.
