The particle-antiparticle asymmetries of Lambda production in 250 GeV/c pi(+/-), K+/-, and p-nucleon collisions are studied with two model parametrizations of quark to Lambda fragmentation functions. It is shown that the available data can be qualitatively explained by the calculated results in both the quark-diquark model and a pQCD based analysis of fragmentation functions. The differences in the two model predictions are significant for K+/- beams, and high precision measurements of the asymmetries with detailed X-F and P-T information can discriminate between different predictions.
