A compilation of the experimental 
data of neutral and charged kaon production has revealed a discrepancy between the observed yield and the the average number of produced charged kaons 
. This widespread relation holds only for a colliding system that is an uniform population w.r. to the isospin (i.e. that consists of an equal number of all members of a given isospin multiplet). This is not the case for collisions therefore one should not expect that it will describe the data accurately. A much better agreement is obtained with a model based on the quark structure of the participating hadrons.
