We present a study of the production of K(S)(0) and Lambda(0) in inelastic p (p) over bar collisions at root s=1800 and 630 GeV using data collected by the CDF experiment at the Fermilab Tevatron. Analyses of K(S)(0) and Lambda(0) multiplicity and transverse momentum distributions, as well as of the dependencies of the average number and < p(T)> of K(S)(0) and Lambda(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(T) distributions extend above 8 GeV/c, showing a < p(T)> higher than previous measurements. The dependence of the mean K(S)(0)(Lambda(0)) p(T) on the charged particle multiplicity for the three samples shows a behavior analogous to that of charged primary tracks.
