The process e⁺e^-→pp¯π⁰ has been studied by analyzing data collected at √s=3.773 GeV, at s√=3.650 GeV, and during a ψ(3770) line shape scan with the BESIII detector at the BEPCII collider. The Born cross section of pp¯π⁰ in the vicinity of the ψ(3770) is measured, and the Born cross section of ψ(3770)→pp¯π⁰ is extracted considering interference between resonant and continuum production amplitudes. Two solutions with the same probability and a significance of 1.5σ are found. The solutions for the Born cross section of ψ(3770)→pp¯π⁰ are 33.8±1.8±2.1 pb and 0.06^+0.10_-0.04^+0.01_-0.01 pb (<0.22 pb at a 90% confidence level). Using the estimated cross section and a constant decay amplitude approximation, the cross section σ(pp¯→ψ(3770)π⁰) is calculated for the kinematic situation of the planned P¯ANDA experiment. The maximum cross section corresponding to the two solutions is expected to be less than 0.79 nb at 90% confidence level and 122±10 nb at a center-of-mass energy of 5.26 GeV.
