The research ought to model the cropping decision making of farmers vis-a-vis diversified crops. A three-stage descriptive model of cropping decision making under uncertainty was developed. The model, which is a modified version of Gladwin's (1980) decision tree model, was tested in six case studies of successful crop diversification in irrigated rice farms. The six case studies consisted of tobacco farming in San Fabian, Pangasinan [Philippines]; tomato growing in Sta. Barbara and Mapandan, Pangasinan; mungbean farming in Manaoag and Urdaneta, Pangasinan; onion growing in San Jose, Nueva Ecija; and garlic, corn, and peanut growing in Laoag, Ilocos Norte. A total of 266 farmers from the different sites were interviewed. Overall, the cropping decision tree model found empirical support in the various cases except for the mungbean case which was not a free choice situation and for the corn and peanut cases which were not the major diversified crops of the farmers but only subsidiary crops. Results indicate that the cropping decision tree model is applicable to the choice of a major diversified crop involving a free choice situation. The model appears promising as a diagnostic guide which can be used by change agents for determining whether or not farmers are ready to crop diversity
