Abstract :
In this paper, the existence of positive periodic solutions to two compete predator-one smith growth for prey model governed by difference equations with ratio-dependent and periodic coefficients is established using the method of coincidence degree, obtain the sufficient conditions which guarantee the existence of the positive periodic solution of the periodic system.
