This research is aimed to determine non-relativistic energy spectra and wave function analysis of Schrodinger equation for Manning-Rosen plus trigonometric Scarf non-central potential and Scarf plus trigonometric Manning-Rosen non-central potential The approximate analytical solution of Schrodinger equation for Manning-Rosen plus trigonometric Scarf non-central potential and Scarf plus trigonometric Manning-Rosen non-central potential are investigated using Romanovski polynomial. The approximate bound state energy eigenvalues are given in the close form, the corresponding approximate radial eigenfunctions is formulated in term of Romanovski polynomials, and the angular wave function is also expressed in term Romanovski polynomial. The effect of the presence of trigonometric potential changes the state of angular wave function level. Keywords: Schrödinger equation, Scarf potential, Manning-Rosen potential, finite Romanovski polinomials method.
