Open Data Kit (ODK) technology was employed to register and collect information about the DVMs. Data forms were designed to collect basic personal and farm characteristics. Location data and a picture of the plot were also collected. The data were collected from vine multipliers that receive regular agronomic support from CIP and/or its partners. The data is updated annually. Contacts and location of DVMs based on the collected location data are posted on the Sweetpotato Knowledge Portal (www.sweetpotatoknowledge.org). The portal targets farmers and/or organizations
interested in finding a multiplier of quality vines.
