A questionnaire was used for data collection which was satisfactory in terms of reliability and validity. The findings revealed that 867 percent of grape growers have access to a moderate level of knowledge about raisin processing and packaging. They have a good knowledge of pre-planting grape and have very little knowledge about packaging and storage of raisin. The respondents have a high level of access to expert grape growers’ among 13 information resources and communication channels. They emphasized on their experience, their relatives’ knowledge and expert grape growers’ as the most important source of knowledge for them.
