Brazil is one of the leading countries in production and exportation of grains. However, most grain production regions in Brazil do not have an adequate storage capacity, which result in losses for the grain supply chain. A possible solution to increase storage capacity is the adoption of on-farm silos. We used the Reasoned Action Approach as a framework to identify the impact of attitude, perceived norms, and perceived behavioral control on farmers’ intention to adopt on-farm silos and to identify the most important beliefs underlying their intentions to adopt it. A survey was conducted with 170 farmers in Brazil. Data was analyzed by means of Partial-Least-Square Structural Equation Modeling and MIMIC models. Results showed that attitude was the main determinant of intention, followed by perceived behavioral control and injunctive norms. Results also showed that “Sell grains at higher price”, “Have independence in relation to grain storage firms”, and “Have control over grain classification” are the most important beliefs that drive attitude; “Bank” is the most important belief that drive perceived norm; and “Have easy access to silos”, “Prioritize other investments”, and “Need skilled workers” are the most important beliefs that drive perceived behavioral control. These results revealed important implications to design public and private interventions aimed to stimulate the adoption of on-farm silos.

巴西是谷物生产和出口的领先国家之一。但是，巴西大多数粮食产区没有足够的储存能力，这导致粮食供应链损失。增加存储容量的一种可能解决方案是采用农场筒仓。我们使用“理性行动方法”作为框架来识别态度，感知规范和感知行为控制对农民采用农场筒仓的意图的影响，并确定其采用该筒仓意图的最重要信念。对巴西的170位农民进行了调查。数据通过偏最小二乘结构方程建模和MIMIC模型进行分析。结果表明态度是意图的主要决定因素，其次是感知的行为控制和禁令规范。结果还表明，“以较高的价格出售谷物”，“相对于谷物储存公司具有独立性”和“对谷物分类具有控制权”是驱动态度的最重要信念。“银行”是推动感知规范的最重要信念；“易于使用筒仓”，“优先考虑其他投资”和“需要熟练工人”是促使人们进行行为控制的最重要信念。这些结果揭示了对旨在刺激采用农场粮仓的公共和私人干预措施的重要意义。“易于使用筒仓”，“优先考虑其他投资”和“需要熟练工人”是促使人们进行行为控制的最重要信念。这些结果揭示了对旨在刺激采用农场粮仓的公共和私人干预措施的重要意义。“易于使用筒仓”，“优先考虑其他投资”和“需要熟练工人”是促使人们进行行为控制的最重要信念。这些结果揭示了对旨在刺激采用农场粮仓的公共和私人干预措施的重要意义。
