We report the measurements of dc-magnetization (M), specific heat (C_{p}) and electrical resistivity (ρ) of an intermetallic URu_{0.68}Pd_{0.32}Ge, that lies at the border between nonmagnetic and magnetic regimes in the magnetic phase diagram of solid solutions URu_{1-x}Pd_{x}Ge. The studied composition shows enhanced dc-magnetic susceptibility χ(T) and the Sommerfeld ratio C_{p}(T)/T at low temperatures. Below 4 K χ(T), C_{p}(T)/T and ρ(T) can be described by χ(T) ∝ T^{-0.48}, C_{p}(T)/T ∝ √T and ρ(T) ∝ c ln(T)+AT^{3/2}, respectively. These observations provide an evidence that URu_{0.68}Pd_{0.32}Ge is a moderately heavy-fermion system with an electronic ground state of non-Fermi liquid character. We found non-linear effect of the magnetization and a large value of the Wilson ratio, which are consistent with the interpretation in terms of magnetic instability.
