HUMAN NUTRITION

Detailed explanation-1: -Other grain legumes, such as peanuts, cowpeas, soybeans, and fava beans, are good nitrogen fixers and will fix all of their nitrogen needs other than that absorbed from the soil.

Detailed explanation-2: -Nitrogen-fixing bacteria (NFB) associate with many grasses, including maize (11, –13), rice (14), sugarcane (15), and Miscanthus species (16). These diazotrophs are endophytic, living between plant cells, and/or epiphytic, living on the surface of plant organs, and most do not elicit plant defense responses (17).

Detailed explanation-3: -These bacteria colonise the roots of the leguminous plants that in response produce a set of new organs called ‘nodules’ on their roots. It is in those nodules that the bacteria fix nitrogen and convert it into ammonia, a compound necessary for plant growth and development.
