The entropy properties are analyzed by Ma's coincidence method in \pi +p and K+p collisions of the NA22 experiment at 250 GeV/c incident momentum. By using the Rényi entropies, we test the scaling law and additivity properties in rapidity space. The behavior of the Rényi entropies as a function of the average number of particles is investigated. The results are compared with those from the {PYTHIA} Monte Carlo event generator.
