Abstract
This article examines the role of potassium fertilizers in extending the storage life and maintaining the postharvest quality of fruits and vegetables. Potassium regulates stomatal function, cell turgor, enzyme activity and membrane stability, thereby influencing firmness, sugar-acid balance, dry matter content and resistance to physiological disorders and d ecay during storage. Data from field and storage trials on potato, tomato, carrot, apple and cabbage are reviewed, comparing potassium chloride, potassium sulfate and potassium nitrate applied at different rates and timings.
