Spelt Spelt Spelt ("Triticum spelta"; "Triticum dicoccum"), also known as dinkel wheat or hulled wheat, is a species of wheat cultivated since approximately 5000 BC. Spelt was an important staple in parts of Europe from the Bronze Age to medieval times; it now survives as a relict crop in Central Europe and northern Spain, and has also found a new market as a 'health food'. Spelt is sometimes considered a subspecies of the closely related species common wheat ("Triticum aestivum"), in which case its botanical name is considered to be "Triticum aestivum" subsp. "spelta". It is a hexaploid wheat, which means
Cover crop ("Sinapis alba") and radish ("Raphanus sativus"). They can be grown after a main (cereal) crop and trap nematodes, for example the beet cyst nematode and Columbian root knot nematode. When grown, nematodes hatch and are attracted to the roots. After entering the roots they cannot reproduce in the root due to a hypersensitive resistance reaction of the plant. Hence the nematode population is greatly reduced, by 70-99%, depending on species and cultivation time. Other cover crops are used to attract natural predators of pests by providing elements of their habitat. This is a form of biological control known as habitat
