Leguminous plants are important in agriculture because(1) They are disease resistant(2) They have high amount of proteins(3) They require less amount of nitrogen for growth(4) Nitrogen-fixing bacteria are symbiotically associated in them

For agriculture, legume plants are important, as they are an essential source of protein for human and animal consumption. This high protein content results from their ability to use atmospheric nitrogen for their nutrition as a result of their symbiotic interaction with rhizobia.
