Search for single top quark and Higgs boson production is among the main goals for the upgraded Tevatron. We study the feasibility of single top quark and Higgs boson search at Tevatron both together since these processes have very similar final state signatures and so backgrounds. Calculation of the cross sections and a detailed analysis of various kinematic distributions for signal and for main backgrounds has been performed. As a result of this study an opimized set of cuts has been worked out for background suppression and for extraction of the signal. This study gives proof to the possibility of testing the nature of the {\wtb} coupling and of a direct measurement of the {\vtb} CKM parameter. The \bbbar -- pair effective mass distribution study allows to extract the signal of Higgs with mass up to about $100\gev$ at $\sqs = 2\tev$ and up to about $120\gev$ at $\sqs = 4\tev$ for integrated luminosity $L= 1000\ipb$.
