For decades, agricultural producers have used bargaining cooperatives as a self-help tool to enhance the income they realize from the sale of their crops. Through group action, these growers have counter-balanced the market power of the large canners and other processors that buy farm produce. This report presents case studies to illustrate historical and contemporary bargaining association activity. Techniques for enhancing the prices growers receive and nonprice services such associations provide their farmermembers are presented. Future challenges and opportunities for producer bargaining associations are also discussed.
