New relations between QCD Borel sum rules for strong coupling constants of K-mesons to baryons are derived. It is shown that starting from the sum rule for the coupling constants g{pi}{sigma}{sigma} and g{pi}{sigma}{lambda} it is straightforward to obtain corresponding sum rules for the gKYN, gKY{xi} couplings, Y = {sigma}, {lambda}.
