Micronutrients are not only essential for plant growth and development but are also integral to human health. Fe and Zn deficiencies cause serious nutritional problems in human beings. Increasing the micronutrient content of grain by bio-fortification offers great potential to combat micronutrient deficiency and dramatically impact human health. To find out the most suitable and profitable method of bio-fortification in aromatic rice with Zinc and Iron, a field experiment was conducted during kharif, 2019 at the Research Farm, Bihar Agricultural University, Sabour, Bhagalpur. The experiment was laid out with Randomized Complete Block Design with treatments comprising of soil and foliar application of Fe and Zn from organic and inorganic sources. Soil application of ZnSO4 and FeSO4 each @ 25 kg ha -1 along with RDF recorded significantly higher plant height, number of tillers hill -1 , leaf area index and dry matter accumulation, highest grain yield (41.30 q ha -1 ), straw yield (59.05 q ha -1 ), net return (65698 Rs. ha -1 ) compared to control. RDF along with foliar application of ZnSO4 and FeSO4 each @ 0.5% at 25 DAT and 1 week after flowering showed similar results as that with soil application of ZnSO4 and FeSO4 each @ 25 kg ha -1 along with RDF with respect to growth, yield and economics of aromatic rice. Foliar application of Zinc & Iron through inorganic sources resulted into better biofortification. T4 (RDF + 2 FS of 0.5% ZnSO4 at 25 DAT & 1 week after flowering) recorded higher Zn content in grain (35.74 mg kg -1 ) and straw (37.93 mg kg -1 ) while T6 (RDF + 2 FS 0.5% FeSO4 at 25 DAT & 1 week after flowering) recorded higher Fe content in grain (74.26 mg kg -1 ) and straw (193.52 mg kg -1 ) followed by T8 (RDF + 2 FS of 0.5% ZnSO4& 2 FS of 0.5% FeS04 each at 25 DAT & 1 week after flowering).
