The increased plant height with application of micronutrients might be due to its role in synthesis of tryptophan which is a precursor of auxin (IAA) and it is essential in nitrogen metabolism which stimulates growth of the plants similarly iron acts as an important catalyst in the enzymatic reactions of the metabolism and would have helped in larger biosynthesis of photo assimilates thereby enhancing growth of the plants., Juhari et al.
