Potato value chain covering certified seed production, multi region cultivation, long term cold storage, French fry and crisp processing, and extensive national distribution.
Explore the 6 stages that make up the Potatoes value chain.
Producers source certified seed potatoes from multiplication schemes that test for virus, bacterial wilt and nematode contamination. Seed potato quality is the single most important input as it determines vigour, yield potential and disease pressure for the entire crop cycle.
Potatoes are cultivated across diverse climatic zones with pivot or drip irrigation and careful late blight management. Soil temperature, hilling practices and irrigation frequency during tuber initiation and bulking directly determine yield, specific gravity and internal quality.
Potatoes are mechanically harvested after chemical or natural vine desiccation to allow skin set. Proper skin set reduces skinning damage during harvest and handling which causes moisture loss, disease entry and reduced storage life.
Potatoes are graded by size, washed for table stock or left unwashed for extended storage at four to seven degrees celsius. Cold storage for up to six months allows consistent year round supply and strategic market release during off season price peaks.
Potatoes are processed into French fries, crisps, dehydrated flakes, frozen products and starch. Processing is the highest value segment of the potato chain and dedicated processing varieties with high specific gravity are contracted separately from table stock production.
Fresh and processed potatoes are distributed through all market channels from informal traders to national supermarket chains and quick service restaurants. Potatoes are the most important vegetable crop in South Africa by production volume and serve as a dietary staple across all consumer segments.
