Potato cultivars for organic farming

摘要

Studies were carried out during 1994-97 at an organic farm in Germany to compare crop yield and crop quality of different potato cultivars. Potatoes were divided according to harvesting date (very early, early, mid-early and mid-late), and cooking types (starch-rich, hard-boiling, and fairly hard-boiling). Highest crop yields were obtained for Junior (very early cv.), Astra, Baronesse and Planta (early cultivars), Raja (hard-boiling cv.), Escort, Treff and Cara (starch-rich cultivars), and Sante (fairly hard-boiling cv.). Nineteen cultivars are described in detail.
