Abstract:	The production of neutral K¹(890) and ρ⁰ mesons was studied in e⁺e^? annihilation at $s =29 GeV$ using the High Resolution Spectrometer at PEP. Differential cross sections are presented as a function of the scaled energy variable z and compared to π⁰ and K⁰ production. The measured multiplicities are 0.84±0.08 ?⁰ mesons and $0.57±0.09 K^{10} (890)$ mesons per event for a meson momentum greater than 725 MeV/c. The ratios of vector meson to pseudoscalar meson production for (u,d), s and c quark are compared to predictions of the Lund model.
