A new measurement of subthreshold K*(892)0 and K0 production is presented. The experimental data complete the measurement of strange particles produced in Al+Al collisions at 1.9A GeV measured with the FOPI detector at SIS at GSI (Darmstadt). The K*(892)0/K0 yield ratio is found to be 0.0315±0.006(stat.)±0.012(syst.) and is in good agreement with the transport model prediction. These measurements provide information on the in-medium cross section of K+- fusion, which is the dominant process in subthreshold K*(892)0 production.
