[en] Results on the investigation of inclusive and semi-inclusive distributions of Λ and K⁰ particles, produced in π^-p interactions at 4.9, 7.5 and 40 GeV/c are presen--ted. It is shown that the inclusive cross section for production of Ksup(0) mesons increases with the energy mainly in the central region, while the inclusive production of Λ hyperons increases in the fragmentation region of the target proton. The normalized structure fucntion PHIsub(x) for K⁰ mesons does not achieve the scaling in the considered energy range, while the function PHIsub(x) for Λ hyperons has the scaling behaviour in a wide range of x, -0.5 < x (<=) 0.1 starting from 4.9 GeV/c
