A field experiment was conducted at Main Agricultural Research Station, Dharwad, to study the agronomic fortification with Zinc and Iron to enhancing micronutrient concentration in sweet corn during Kharif 2015.-16 and 2016-17. The field experiment was laid out in split plot design with three replications and 21 treatment combinations involving three main and seven subplots. The pooled results indicated that, soil application of ZnSO4 and FeSO4 (10 kg each ha-1) fortified with vermicompost (250 kg ha-1) along with foliar application of ZnSO4 and FeSO4 (1.0 % each) at 20 and 40 days after sowing were recorded significantly higher zinc and iron concentration in grain and fodder during both seasons, which was on par with treatment combination of soil application of ZnSO4 and FeSO4 (10 kg each ha-1) fortified with farm yard manure (500 kg ha-1) along with foliar application of ZnSO4 and FeSO4 (1.0 % each) at 20 and 40 days. Similarly, significantly higher micronutrients uptake was also observed in above said treatments as compared to no fortification and no foliar application of micronutrients.
