Data are presented on inclusive single particle distributions in the proton fragmentation region for the reactions K +p → π ±X at 8.2 and 16 GeV/ c and K −p → π ±X at 10 and 16 GeV/ c. The energy dependence is studied and compared with the dual Regge model predictions for approach to scaling. None of the existing models is in full agreement with the data. The model of Chan and his collaborators is consistent with our results under the additional assumption of equality of vector and meson coupling constants in the p π + vertex in the Mueller diagram.
