  We consider generation of baryon asymmetry of the universe through $R-$parity
violation in a scenario in which out-of-equilibrium condition is satisfied by
making the electroweak phase transition to be first order. We study all the
$R-$parity violating interaction which can generate $(B-L)$ asymmetry which
then converts to baryon asymmetry of the universe. We demonstrate that
CP--violating sfermion deudy all the $R-$parity violating interaction which can
generate $(B-L)$ asymmetry which then converts to baryon asymmetry of the
universe. We demonstrate that CP--violating sfermion decays contribute more
than that of the neutralino decays in the generation of $(B-L)$ asymmetry.
