The production of neutral strange hadrons is studied using deep-inelastic events measured with the H1 detector at HERA. The measurements of and productions are made in two regions of phase space defined by the negative four-momentum transferred squared of the photon, 7 < Q2 < 100GeV2 and the inelasticity 0.1 < y < 0.6 for the and 145 < Q2 < 20000GeV2 and 0.2 < y < 0.6 for the Λ . and production cross sections are determined. Differential ratios of production to charged hadron production are measured. Differential yields per event are determined. The Λ − asymmetry is measured and found to be consistent with zero. Predictions of leading order Monte Carlo programs are compared to data.
