In this paper, we study the singular semi-positone Neumann bound\-ary-value problem
where is a positive constant. Under some suitable assumptions on the functions and , for sufficiently small , we prove the existence of a positive solution. Our approach is based on the Krasnasel'skii fixed point theorem in cones.
