Bianchi Type II dust filled universe with time dependent cosmological term (L) in presence of C-field (Creation field cosmology) is investigated. To get the deterministic solution, we have also assumed that s a q where s is shear and q the expansion in the model. This leads to A = Bn where A and B are metric potentials and n is a constant. To find the solution in terms of cosmic time t, we have assumed n = 1/2. The solution so obtained satisfies conservation equation (8pi GTji + /gji ) =0which leads to C = t. Thus C increases with time, which agrees with creation field cosmology. The deceleration parameter q > 0 represents decelerating phase. It gives the significance to study early universe. The cosmological constant (L) decays with time which agrees with the present day observations of the universe. The other physical aspects of the model are also discussed.
