Question

Why is it not necessary to add nitrogenous fertilizer for the cultivation of

pulses(leguminous)?​

Answer 1

Answer:

Legume crops contain the nitrogen fixing bacteria (Rhizobium spp.) ... These bacteria fix atmospheric nitrogen into nitrates for the plant use. Hence, supply of nitrogenous fertilizers to the leguminous crops is not necessary.

Explanation:

Answer 2

Answer:

The nitrogen-fixing bacteria (Rhizobium spp.) are found in the root nodules of legume crops. For the benefit of plants, these bacteria convert atmospheric nitrogen into nitrates. Therefore, it is not necessary to feed nitrogenous fertilizers to leguminous crops.

Explanation:

• Because the roots of leguminous plants have a symbiotic relationship with a bacterium known as Rhizobium, which fixes atmospheric nitrogen into the soil, farmers do not apply fertilizers when growing leguminous crops.
• Pod-bearing plants are known as legumes. They differ significantly from grasses, cereals, and other non-legume crops in that a large portion of the nitrogen they need is created by bacteria in nodules on their roots, which fix nitrogen from the atmosphere. Legumes are hence high in protein.
