Schulte-Geldermann, Elmar[Tackling low potato yields in Eastern Africa: an overview of constraints and potential strategies.]Tackling low potato yields in Eastern Africa: an overview of constraints and potential strategies.

One of the most important constraints to potato production in developing countries is the lack of quality planting material to be used by farmers, either coming from the formal or from farmer-based seed systems. A number of projects have been implemented to improve farmers' access to quality plan...

Scarcity of good quality seed is major obstacle to expanded potato (Solanum tuberosum L.) production in sub-saharan Africa (SSA). Constraints in availability and supply of seed potato are partly attributable to challenges in production of pre-basic which is an intermediary step necessary in produ...
