The production of charged {rho} mesons on nuclei and nucleons is investigated in charged current neutrino interactions at moderate energies (} Almost-Equal-To 10 GeV), using the data obtained with SKAT bubble chamber. No strong nuclear effects are observed in {rho}{sup +} and {rho}{sup -} production. The fractions of charged and neutral pions originating from {rho} decays are obtained and compared with higher-energy data. From analysis of the obtained and available data on {rho}{sup +} and K*{sup +}(892) neutrino production, the strangeness suppression factor is extracted: {lambda}{sub s} = 0.18 {+-} 0.03. Estimation is obtained for cross section of coherent {rho}{sup +} neutrino production on nuclei.
