Solution and Explanation
The organism directly associated with nitrogen fixation in pulses is Rhizobium.
Rhizobium is a genus of bacteria that forms a symbiotic relationship with leguminous plants such as peas, beans, lentils, and pulses.
These bacteria infect the root hairs of the host plant and form specialized structures called root nodules.
Inside the nodules, Rhizobium converts atmospheric nitrogen (N2) into ammonia, which the plant can absorb and use for growth.
This natural nitrogen-fixing process reduces the need for synthetic nitrogen fertilizers, saving costs and maintaining soil fertility.
Rhizobium biofertilizers are widely used in sustainable agriculture to enhance nitrogen availability for legume crops.
