Abstract: A field experiment on agronomic bio fortification of zinc and iron micronutrients in maize was carried out during kharif season of 2015 at Agricultural Research Station, Bail hongal. The experiment laid out in randomized block design with factorial concept with three replications consisted of 16 treatment combinations involving seed treatment (no seed treatment and seed treatment with Zn and Fe each 1 ), soil application of Zn and Fe (no soil application, soil application of recommended ZnSO4 and FeSO4 each 25 kg ha-1 and FYM enriched ZnSO4 and FeSO4 application each 15 kg ha-1 and FYM enriched ZnSO4 and FeSO4 application each 25 kg ha-1) and foliar application of Zn and Fe at 45 DAS (no foliar and foliar spray of ZnSO4 and FeSO4 each 0.5 ). Significantly higher Zn (47 mg kg-1) and Fe (75.2 mg kg-1) density in maize grain was recorded with soil application of FYM enriched ZnSO4 and FeSO4 each 25 kg ha-1 than control. And it was on par with the soil application of FYM enriched ZnSO4 and FeSO4 each 15 kg ha-1.
