We present a study of the production of K{sub S}{sup 0} and {lambda}{sup 0} in inelastic pp collisions at {radical}(s)=1800 and 630 GeV using data collected by the CDF experiment at the Fermilab Tevatron. Analyses of K{sub S}{sup 0} and {lambda}{sup 0} multiplicity and transverse momentum distributions, as well as of the dependencies of the average number and <p{sub T}> of K{sub S}{sup 0} and {lambda}{sup 0} on charged particle multiplicity, are reported. Systematic comparisons are performed for the full sample of inelastic collisions, and for the low and high momentum transfer subsamples, at the two energies. The p{sub T} distributions extend above 8 GeV/c, showing a <p{sub T}> higher than previous measurements. The dependence of the mean K{sub S}{sup 0}({lambda}{sup 0}) p{sub T} on the charged particle multiplicity for the three samples shows a behavior analogous to that of charged primary tracks.
