Vicia sativa known as the common vetch, garden vetch, tare or simply vetch

Vicia sativa (known as the common vetch, garden vetch, tare or simply vetch) – Fabaceae, 

a common winter weed in north India. It is also cultivated in limited regions due to anti-nutritional compounds in the seed although it is grown in dryland agricultural zones in Australia, China and Ethiopia due to its drought tolerance and very low nutrient requirements compared to other legumes. In these agricultural zones common vetch is grown as a green manure, livestock fodder or rotation crop.
