  In this article, some factorization properties of polynomials over discrete
valuation domains are elucidated. These properties along with the notion of
Newton index of a polynomial leads to a generalization of the main result
proved by \c{S}tef\u{a}nescu [`On the factorization of polynomials over
discrete valuation domains', \emph{Versita} \textbf{22}:1 (2014), 273--280].
