摘要
There is potential for expanding production and marketing of sweetpotatoes in southern Illinois because they are readily grown organically or with minimal pesticide applications and are a highly nutritious alternative staple food. Two experiments measured: (1) attitudes and consumption behavior about sweetpotatoes of consumers in supermarkets and direct market venues; and (2) effect of planting date and cultivar/clone on yield distribution at two locations over three years. Consumers express strong interest in sweetpotatoes, but consume very few. Most purchased sweetpotatoes at supermarkets (53%), followed by direct markets (34%) and rarely restaurants (2%). Diverse demographics and traditions of use caused sharply contrasting attitudes about the utility and value of sweetpotatoes, new methods of educating consumers, e.g., point of purchase materials (recipes), are required to expand market potential. 'Beauregard' clones, 'B14' and 'B73', increased marketable yields from 3,000 to 11,500 lb/acre over that of 'Hernandez'. Planting by mid-June produced the highest marketable yields.

那里，因为他们很容易被有机增长或轻微农药的应用，是一个高营养替代主食是潜在的扩大生产和销售sweetpotatoes在伊利诺斯州南部。两个实验测得：（1）态度和有关消费者在超市和市场直接场地sweetpotatoes消费行为;和播期和品种/在三年以上两个地点的克隆对产量分布（2）效果。消费者表达sweetpotatoes浓厚的兴趣，但消耗很少。超市（53％25）购买大部分sweetpotatoes，其次是直接的市场（34％25），很少餐厅（2％25）。不同的人口统计和使用传统造成尖锐对立有关实用程序和sweetpotatoes，消费者教育的新方法，如价值观念，点购料（菜谱），都需要拓展的市场潜力。“博勒加德克隆B14和B73，增加适销对路的产量从3000 11500磅/英亩以上的”埃尔南德斯的。通过种植六月中旬的生产适销对路的最高收益率。
