What are the Uses of Legumes?

Legumes

Legumes are plants that belong to the Fabaceae (Leguminosae) family. They are grown primarily for human consumption, feeding livestock and manuring purposes. Their different forms include pulses, beans and lentils. It is a major source of proteins, vitamins, carbohydrates and fibres. So they are included in the staple diet all over the world.

The dried seeds of legumes are known as pulses. Examples of pulses include chickpeas, soybeans, red kidney beans etc.

Uses

  • Pulses such as chickpea and cowpea are used as daily dietary food by humans.
  • Groundnut and soybeans are used for the extraction of oils.
  • They are used as a substitution food by vegans and lactose-intolerant people.
  • The forage produced by the leguminous plants is used for feeding the livestock.
  • Indigofera and acacia species are used to extract gums and dyes.

Nitrogen Fixation

Many legumes form symbiotic relationships with bacteria called Rhizobia at their root nodules and help in the fixation of atmospheric nitrogen. They convert the molecular nitrogen to a simpler form of ammonia, which is then converted to ammonium, that can be taken up easily by the plants. Thus the root nodules are a rich source of proteins.

Crop rotation is practised in agriculture, where leguminous and non-leguminous plants are grown alternatively. This way, the soil receives enough amount of nitrogen to produce both types of crops.
