Using the data obtained with the SKAT bubble chamber, the total yields of K*(892){sup +}, {sigma}{sup +}(1385), and {sigma}{sup 0} are estimated for the first time in neutrino-induced reactions at moderate energy <E{sub v}> = 10.4 GeV. It is shown that the recently observed enhancement of the K{sup 0} and {lambda} yields in vA interactions as compared to vN interactions is contributed only slightly by the K*(892){sup +} and {sigma}{sup +}(1385) production. The contribution of resonances to the K{sup 0} and {lambda} yields is found to be in qualitative agreement with higher energy (<E{sub v}> {>=} 40 GeV) data. It is shown that the energy dependence of the K*(892){sup +} mean multiplicity in vN interactions is approximately linear in the range of <E{sub v}> {approx} 10-60 GeV, while that for {sigma}{sup 0} in vA interactions (A = 20-21) is approximately logarithmic in the range of <E{sub v}> {approx} = 10-150 GeV.
