GENERAL KNOWLEDGE

Detailed explanation-1: -Legume crops such as beans, peanuts and soy can fix nitrogen from the air, and flourish on nitrogen-deficient soils. To do so, they need help from Rhizobium bacteria. These special bacteria stimulate the growth of nodules on the roots of leguminous plants.

Detailed explanation-2: -Nodules apparently help the plant use fertilizer nitrogen efficiently. 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-3: -The mung bean has a great potential under tropical conditions given its high content of grain protein. Additionally, its ability to benefit from biological nitrogen fixation (BNF) through association with native rhizobia inhabiting nodule microbiome provides most of the nitrogen independence on fertilizers.

Detailed explanation-4: -Gardeners can feed their families and enrich the soil by growing legumes, such as green beans, soybeans, lentils and peas. Legume roots produce their own nitrogen, which is a major fertilizer nutrient needed by all plants for growth.
