Vicia ervilia, called ervil[1] or bitter vetch, is an ancient legume crop of the Mediterranean region.
[2] The nutritional value of the grain for ruminant cattle has guaranteed the species' continued cultivation in Morocco, Spain and Turkey.
It has been held in high esteem by farmers in the Old World since the beginning of agriculture to improve the nutritional value of bulk feeds.
[3] The wild strains of bitter vetch are limited to an area that includes Anatolia and northern Iraq, with an extension south along the Anti-Lebanon Mountains of Syria and Lebanon.
Traces of the earliest domesticated instances were recovered from several archeological sites in Turkey, with an uncorrected radiocarbon dating of the 7th and 6th millennia BC.
