The studies of hyperon production performed at COSY-11 are summarized. The results of the experiments in the reaction channels pp{yields}pK{sup +}{lambda}, pp{yields}pK{sup +}{sigma}{sup 0}, and pp{yields}nK{sup +}{sigma}{sup +} are shown. Excitation functions from threshold up to about 90 MeV excess energies have been evaluated with high precision for the {lambda} and {sigma}{sup 0} production. The {lambda}p and {sigma}{sup 0}p final state interactions were extracted. The {sigma}{sup +} production was measured at 13 and 60 MeV excess energies.
