The first stable product of fixation of atmospheric nitrogen in leguminous plant is

Step-by-step solution

The fixation of atmospheric nitrogen to ammonia is given as N ₂+8 e ⁻+8 H ⁺+16 ATP [ Nitrogenase ] MO - Fe 2 NH ₃+ H ₂+16 ADP +16 Pi The process in which atmospheric nitrogen gets concerted into inorganic nitrogenon (nitrate, ammonia) compounds through microorganisms is called biological nitrogen fixing.
