Fisher equation is nonlinear partial differential equation which is used in various biological, chemical processes in engineering and sciences. In this paper, we use the numerical technique, Variational iteration method and its some sub sequenced modification to solve the Fisher’s equation. Lagrange multipliers for identification of optimal value of parameters in a functional are the basis of Variational iteration method. This method can be used to find possible approximate or series solution of problem. This paper also contains the numerical solution of Fisher equation. The Important purpose of this paper is to check the reliability of these techniques for the solution of Fisher equation as compared to other techniques.
