We study the three-body baryonic decay B0→Λ+c p π0 based on the factorization approach. The most important Feynman diagrams for this decay mode are factorizable and non-factorizable contributions, so that the former plays the key role in the decay amplitude and the latter affects the amplitude coefficient a2. We calculate the decay branching ratio for some values of a2 in the range of 0.16-0.40 and we find that the value of a2=0.17 leads us to the result of (1.50±0.21)×10-4 which evidently agrees with the experimental result (1.55±0.17±0.08)× 10-4 reported by BABAR
