Resumen
Descripción
Increased sweetpotato production in sub-Saharan Africa is hampered by high incidence of virus diseases. Work is going on to test whether healthy seed production can be maintained through a combination of farmer practices and internal and external quality assurance mechanisms; and to ensure that external regulatory processes are appropriate and cost effective. This will generate evidence about the effectiveness of the net tunnel technology in enhancing farmers’ access to quality planting material. This flyer outlines the approaches and lessons learnt so far in research and dissemination of net tunnel technology in Tanzania and Uganda.
