In the present work, we compare the radiative transition rates computed by two different semi-empirical approaches, based on a parametrization of the oscillator strengths and on a pseudo-relativistic Hartree-Fock model including core-polarization effects, for spectral lines in singly ionized zirconium. A detailed comparison with available experimental results is also reported and an overall good agreement is observed between all sets of data allowing us to provide new reliable oscillator strengths for a large amount of Zr II lines in the wavelength region from 1616 to 14746 angstrom. Moreover, we give radial integral values of the main atomic transitions deduced in this study: < 4d(2)5p vertical bar r(1)vertical bar 4d(2)5s >) = -3.1522 (0.0161), < 4d(2)5p vertical bar r(1)vertical bar 4d(3)> = 1.7605 (0.0107), < 4d(2)5p vertical bar r(1)vertical bar 4d(2)6s > = -1.481 (0.794) and < 4d(2)5p vertical bar r(1)vertical bar 4d(2)5d > = 2.289 (0.014).
