Gravitational baryogenesis is one of the mechanisms which help us to explore more about our early universe, especially baryon-anti-baryon asymmetry. As we know, modified theories gravity are very successful in describing present accelerated scenario universe. Therefore, this letter, aim constrain generalized torsion-based theory gravity, namely, $f(T,\mathcal{T})$ with gravitational baryogenesis, where $T$, $\mathcal{T}$ torsion scalar, trace energy-momentum tensor, respectively. For this, examine how various Lagrangian forms affect baryogenesis. We also impose constraints on extra degrees freedom induced by observational values baryon-to-entropy ratio. In addition, further can attribute a physically viable and consistent way cosmologies gravity.
