Yield

Congo had average to below average yields at the two growing sites, with .61 kg/plant in Victoria and .53 kg/plant in Caledon. It is likely that yields would have been higher in Caledon had the potatoes been left to grow through to maturity.

Discussion

Congo is a late heritage variety that is valued for its rich purple colour and waxy flesh. Yield results indicate that it may be a reliable performer under a wide variety of conditions.
