We present measurements of ρ⁰, ω and K^{∗ 0} spectra in π^-+ C production interactions at 158 GeV/c and ρ⁰ spectra at 350 GeV/c using the NA61/SHINE spectrometer at the CERN SPS. Spectra are presented as a function of the Feynman’s variable x_F in the range 0 < x_F< 1 and 0 < x_F< 0.5 for 158 and 350 GeV/c respectively. Furthermore, we show comparisons with previous measurements and predictions of several hadronic interaction models. These measurements are essential for a better understanding of hadronic shower development and for improving the modeling of cosmic ray air showers.
