The purpose of this study was to find out the influence of attributes of rubber technologies on adoption in Indonesian rubber smallholdings. A sample of 257 respondents from three groups of stakeholders was studied for their opinions regarding technology attributes, knowledge, and adoption of recommended technologies, and reasons for non-adoption. Data were gathered using a mailed questionnaire, and individual and group interviews. It was concluded that some rubber research technologies are inappropriate for smallholders’ conditions because technological attributes can impede adoption. Follow-up pilot participatory research projects were developed which can enable rubber research providers to improve the appropriateness of recommended technologies.
