Cosmic inflation in LRS Bianchi Type I space-time under effect of the bulk viscosity and time dependent cosmological constant in C-field cosmology is investigated. To find the deterministic result of the field equations, we assumed R where H0 is the Hubble parameter and t is cosmic time. It has been observed that the C-field effect increases with cosmic time, and the obtained result resembles the evidence in HN theory. The real singularity does not exist in the derived model and Particle horizon exists in the model. The spatial volume increases in exponentially manner with proper time favorable to the expansion of the universe. The negative deceleration (q  0) indicates the accelerated phase of the universe and the de-sitter cosmos is investigated. The bulk viscosity coefficient is found to be constant and vacuum energy density found to be negatively in exponential manner with cosmic time which shows that the decay of the energy component transfers energy in a continuous way to the material component.The volume of cosmos varies as exponentially way to proper time along with hubble parameter. The geometrical and dynamical properties of physical parameter are investigated in rigorous manner. The behavior of the model under different physical conditions is also discussed.
