Abstract Results onK 0 and Λ production ine + e − annihilation at c.m. energies of 14, 22 and 34 GeV are presented. The shape of theK 0 and Λ differential cross sections are very similar to each other and to those of π±,K ± and $$p(\bar p)$$ . Scaling violations are observed forK 0 production. We obtain a value for the probability to produce strange quark-antiquark pairs relative to that to produce up or down quark-antiquark pairs of 0.35±0.02±0.05. The value ofR h =σ(e + e -→hX)/σµµ is shown to rise steadily with c.m. energy for all particle species. At 34 GeV we find 1.48±0.05K 0 and 0.31±0.03 Λ per event. We have searched for possible Λ polarization. The production ofK 0's and Λ's in jets is examined as a function ofp T 2 and rapidity and compared to that of all charged particles; the yields in two and three jets are also investigated. Results are presented from events with two baryons $$(\Lambda ,\bar \Lambda ,por\bar p)$$ observed.
