Query: Starobinsky model with f-essence   In this paper, we consider a cosmological model of the flat and homogeneous
universe for the Starobinsky model $F(R)=\alpha R + \beta R^{2}$, which is
non-minimally coupled with f-essence. For this model we obtained the field
equations and considered particular solutions of the coupling and fermionic
field functions. It is shown that the fermionic field can describe a nature of
the universe.
