The reaction mechanisms for K{sigma}(1385) photoproduction from the reaction {gamma}p{yields}K{sup +}{sigma}{sup 0}(1385) in the resonance energy region are investigated in a hadronic model. Both contributions from N and {delta} resonances of masses around 2 GeV as given in the Review of Particle Data Group and by the quark model predictions are included. The Lagrangians for describing the decays of these resonances into K{sigma}(1385) are constructed with the coupling constants determined from the decay amplitudes predicted by a quark model. Comparing the resulting total cross section for the reaction {gamma}p{yields}K{sup +}{sigma}{sup 0}(1385) with the preliminary data from the Thomas Jefferson National Accelerator Facility, we find that the most important contributions are from the two-star-rated resonances {delta}(2000)F{sub 35},{delta}(1940)D{sub 33}, and N(2080)D{sub 13}, as well as the missing resonance N(3/2){sup -}(2095) predicted in the quark model. Predictions on the differential cross section and photon asymmetry in this reaction are also given.
