In the present paper, we report the observation of Meyer-Neldel rule for the non-isothermal crystallization of glassy Se$_{70}$Te$_{30 - x}$Ag$_{x}$ alloys. We have observed a strong co-relation between the pre-exponential factor $K_{0}$ of rate constant $K(T)$ of crystallization and activation energy of crystallization $E_{c}$ in the present case. This indicates the presence of compensation effect for the non-isothermal crystallization process in the present glassy system.
