Using the data obtained with SKAT bubble chamber, the total yields K+(892), Sigma+(1385) and Sigma0 are estimated for the first time in neutrino-induced reactions at moderate energy < E_nu > = 10.4GeV. It is shown, that the recently observed enhancement of the K0 and Lambda in nu A interactions as compared to nu N interactions is contributed only slightly by the K+(892) and Sigma+(1385) production. The contribution of resonances to the K0 and Lambda yields is found to be in qualitative agreement with higher energy (< E_nu > geq 40 GeV) data. It is shown, that the energy dependence of the K+(892) mean multiplicity in nu N interactions is approximately linear in the range of < E_nu > approx 10-60 GeV, while that for Sigma 0 in nu A interactions (A = 20-21) is approximately logarithmic in the range of < E_nu > \approx 10-150 GeV.
