Abstract: Deficiency of micronutrient in soils of Asian continent including Pakistan is widespread due to alkaline and calcareous nature of soils. Therefore, in these regions Bio-fortification of crops with micronutrients is considered as a significant technique to improve nutritional value in cereal grains like wheat and rice. A field study was performed during the year of 2018-2019 to ascertain the effect of zinc and iron supplementation in wheat crop using three different modes of application in Sargodha region of Pakistan. Research was comprised of seven treatments along with required doses of NPK (120:80:60) as T1 as control, T2-T5 as soil fertilization with zinc and iron in different ratios T6 as Foliar spray of micronutrients (Zn and Fe), T7 as seed priming with solution of zinc and iron. Field was designed as Randomized complete block design (R.C.B.D).All the growth and physiochemical attributes of study were analyzed in laboratory of Soil Science Department of College of Agriculture, University of Sargodha, Pakistan. It was evident from the results that fertilization of Zn and Fe through soil in high amount (T5) influence the concentration of Zn and Fe in wheat grains and plant biomass significantly as well as also increase the other growth parameters such as plant height, spike length, biomass of plant, grain yield, 1000 grain weight and protein contents. Similarly results of foliar application of Zn and Fe (T6) and seed priming (T7) were also at par.
