Mangelwurzel

Mangelwurzel or mangold wurzel (from German Mangel/Mangold, "chard" and Wurzel, "root"), also called mangold, mangel beet, field beet, fodder beet and (archaic) root of scarcity, is a cultivated root vegetable. It is a variety of Beta vulgaris, the same species that also contains the red beet (beetroot) and sugar beet varieties. The cultivar group is named Crassa Group. Their large white, yellow or orange-yellow swollen roots were developed in the 18th century as a fodder crop for feeding livestock.
