[citation needed] The wild and domesticated landraces of Crotalaria tetragona, colloquially known as "Tum-thang", are grown and eaten by the tribal communities of the Mizoram state of North-east India.

[3] In the Lake Victoria basin of East Africa, the wild and cultivated lines of Crotalaria brevidens, also known as “mitoo,” are harvested and eaten as a leafy vegetable in many popular cuisines.

[4] Crotalaria longirostrata, also known as longbeak rattlebox or chipilín, is found in Guatemala, El Salvador, and Oaxaca and is a popular addition to many local dishes.

The foliage contains high amounts of calcium, iron, thiamine, riboflavin, niacin, and ascorbic acid, while the seeds and roots are considerably toxic.

[5] Crotalaria longirostrata is considered a noxious weed in the United States since it is avoided as a source of consumption by many animals and since its seeds shatter and spread over a wide range.

Australian species of the genus Crotalaria have the capacity to be cultivated into potential grain crops that are adapted to dry environments, nutrient poor soils, and low-input agricultural systems.

Australian Crotalaria species also show many suitable traits of harvestability, including an upright growth habit, a low tendency to dehisce and shatter, the bearing of its fruits and flowers at the ends of branches, and large to moderate seeds.

Crotalaria juncea, also known as sunn hemp, is currently grown throughout the tropics and subtropics[7] as a source of green manure, lightened fiber, and fodder.
