A study of strange particle production in ν μ charged current interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particles (K 0 s ,Λ,) have been measured. Mean multiplicities are reported as a function of the event kinematic variables E ν , W 2 and Q 2 as well as of the variables describing particle behaviour within a hadronic jet: x F , z and p T 2 . Decays of resonances and heavy hyperons with identified K 0 s and Λ in the final state have been analyzed. Clear signals corresponding to K * + /-, Σ * + /-, Ξ - and Σ 0 have been observed.
