The experimental data from the 2 m propane bubble chamber have been analyzed for pC{yields} {lambda}(K{sub s}{sup 0})X reactions at 10 GeV/c. The estimation of experimental inclusive cross sections for Lgr; and K{sub s}{sup 0} production in the p12C collision is equal to {sigma}{lambda}= 13.3{+-}1.7 mb and {sigma}{sub K{sub s}{sup 0}}= 3.8{+-}0.6 mb, respectively.The measured {lambda}/{pi}+ ratio from pC reactions is equal to (5.3{+-}0.8) * 10-2. The experimental {lambda}/{pi}+ ratio in the pC reaction is approximately two times larger than the {lambda}/{pi}+ ratio from pp reactions. There is a significant enhancement specially in the {lambda}/{pi}+ ratio for p+C and C+C collisions at 10 A{center_dot}GeV/c.The investigation has been performed at the Veksler and Baldin Laboratory of High Energies, JINR.
