Abstract :

All plants utilize nitrogen (N) in the form of N[O.sub.3.sup.-] and N[H.sub.4.sup.+]. It is most imperative element for proper growth and development of plants which significantly increases and enhances the yield and its quality by playing a vital role in biochemical and physiological functions of plant. Pivotal N is required in larger quantity about 1000 ug [kg.sup.-1] dry matter, so, it is compulsory supplied to plants. It is top most 100% deficient in Pakistani soils due to low organic matter content, additionally, various factors are associated with the insufficiency such as improper application, methods, timings and harvesting causes losses through volatilization, leaching, denitrification and crop removals etc. An estimate 78-79% N is available in the atmosphere in inert structure ([N.sub.2]) that is not useful for plants, and thus not up-taken directly. N is available from industrial, atmospheric and biological as well as organic fixation. Therefore, nutrient management practices should be technical and most advantageous. This review research paper is lighting up with full spectrum on the role of N for plants and providing a beneficial knowledge to the farmers, students and researchers. Furthermore, in this detailed review, it was concluded that nitrogen greatly contributes in agriculture. Only big cause of limited yield with lower most quality of crops throughout the world is due to improper and non-judicious use of N and its reason is lack of awareness.
