Replication Data for: Marando Bora Decentralised Vine Multiplier Study (Tanzania) uri icon


  • The implementation of the large- scale planting material dissemination component, “Marando Bora” (better vines) aimed to develop and test cost effective sweetpotato variety distribution models at scale. Marando Bora had a target of reaching 150,000 farmers with quality planting material of existing local and improved varieties which will contribute to strengthened food security. The survey of decentralised vine multipliers (DVMs) was conducted as part of the Marando Bora project end line survey. The objectives of the DVM module were to: determine use of different technologies which had been promoted by the project; obtain feedback on varieties preferred by the DVMs and their clients; and feedback on participation in the pilot Quality Declared Planting Material (QDPM) inspection scheme. Finally, we sought to understand what vine multiplication activities the DVMs were continuing after the end of the project, and their reasons for continuing or not continuing vine multiplication. Key variables include: DVM location, type (individual, group), current multiplication practice, technologies (irrigation, rapid multiplication techniques, fertiliser), experience with seed inspection. All 89 DVMs were interviewed by one data collector, February-March 2013. Data was entered in MS Excel.
