We examine the effect of adding mesons f0(975) and φ(1020) as well as the variety of U(N)[I](the potential well depth of [I] in nuclear matter) from -10 MeV to -28 MeV on the extent of the particles participation and the properties of the neutron star in the relativistic mean fidd model. We find that considering the contribution of f0 and φmesons, the equation of state of the neutron star turns soft, the maximum mass reduces while the corresponding radius increases. [I]- hyperons appear at lower density as U(N)[I] becomes deeper, and the variety of U(N)[I] has little effect on the equation of state and the properties of the neutron star.
