We have obtained a semi-analytical solution of GLR-MQ-ZRS equation at small x for gluon density using Regge like ansatz of G ( x,Q 2 ) in the leading twist approximation. It is observed that, our solution is valid in the vicinity of saturation scale where modification in the QCD evolution can not be ruled out due to salient gluon fusion processes. Our computed results of nonlinear gluon density are then compared with different global parameterizations and it is enticing to note that, the rapid growth of gluon densities towards small- x is tamed due to the nonlinear corrections.
