In the present paper, we establish a Chen–Ricci inequality for a C-totally real warped product submanifold of Sasakian space forms . As Chen–Ricci inequality applications, we found the characterization of the base of the warped product via the first eigenvalue of Laplace–Beltrami operator defined on the warping function and a second-order ordinary differential equation. We find the necessary conditions for a base of a C-totally real-warped product submanifold to be an isometric to the Euclidean sphere .
