Field Characters

Leaflets 1-nerved beneath, fruit shallowly scalloped along one side. A. americana has 2-3 nerves on its leaflets and is deeply scalloped along one side of its fruit.

Cultural Information

Mechanical scarification of hand-harvested seed may be necessary to overcome hard seededness. A. indica appears to be somewhat promiscuous, but may nodulate more effectively with CB 2312. Can form nodules at the base of the stem.

Animal Use

Low to moderate palatability. There is evidence of toxicity to ruminants. Seeds as contaminants in feed grain can be toxic to pigs, causing a vestibulocerebellar disorder.

Natural History

A colonizing annual that will be present in early successional stages and as a result of disturbance.

Habitat

Wet coastal areas on soils with texture ranging from sandy loam to clay, with pH from 4.5-8; sometimes on black saline soils. Distribution more determined by moisture availability and drainage than by soil texture. Mostly on soils that are subject to flooding and waterlogging .

Plant Uses

A freely nodulating nitrogen-fixing species, A. indica can be used as green manure. May have application as a fodder crop in rotation with rice, but should be treated with caution due to reports of toxicity. Many medicinal uses (including spermicide). Pith from the stem can be used for floatation. Low to moderate palatability. There is evidence of toxicity to ruminants. Seeds as contaminants in feed grain can be toxic to pigs, causing a vestibulocerebellar disorder.
