The main objective of this article is to analyze the baryogenesis of the universe in the framework of f(R, T, X) gravity under an isotropic universe model, where R and T represent the Ricci scalar and the trace of the energy–momentum tensor (EMT), respectively, and 
. We explore baryogenesis with non-minimal (NM) coupling through the contraction of the Ricci tensor and EMT. For this, we use dust and stiff-type fluids with power-law and de-sitter-type solutions of the scale factor. In the end, we compute the baryon asymmetry factor (BAF) for some recently proposed models of this gravity, and then we compare our findings with observational limits on BAF. We also discuss the generalized gravitational baryogenesis in detail. After analysis, we conclude that this gravity is reliable for baryogenesis in some subspaces of the model parameter space.
