It is well-known that a ring R is right Noetherian if and only if every direct sum of injective right R-modules is injective. In this paper, we characterize Nonnil-Noetherian rings by nonniMnjective modules. If R is a commutative ring, then we prove that R is a Nonnil-Noetherian ring if and only if the ring R[x]/(xn+1) is Nonnil-Noetherian, where (xn+1) is the ideal generated by xn+1 and n is a non-negative integer.
