  In this study, we comprehensively investigate the production of isovector
scalar meson $a_{0}(1817)$ using the effective Lagrangian approach.
Specifically, we employ the Reggeized $t$ channel Born term to calculate the
total and differential cross sections for the reaction $K^{-}p \rightarrow
a_{0}(1817)\Lambda$. Our analysis reveals that the optimal energy range for
detecting the $a_{0}(1817)$ meson lies between $W=3.4$ GeV and $W=3.6$ GeV,
where the predicted total cross section reaches a minimum value of 112 nb.
Notably, the $t$ channel, as predicted by the Regge model, significantly
enhances the differential cross sections, particularly at extreme forward
angles. Furthermore, we investigate the Dalitz processes of $2\rightarrow 3$
and discuss the feasibility of detecting the $a_{0}(1817)$ meson in experiments
such as J-PARC.
