The pion-nucleon sigma term is calculated in the framework of the quark model and current algebra using the parameter of violation of the Okubo-Zweig-Iizuka (OZI) rule. The calculation makes use of the interval of values for the current-quark mass ratio m/sup T//sub S// m/sup T/ calculated in the framework of current algebra and PCAC. Using the quark-parton model, an estimate is given for the parameter of violation of the OZI rule.
