Abstract: A field experiment was conducted at ARS, Hagari on medium black soil during rabi-2017 to study the effect of agronomic fortification with zinc and iron on growth parameters and yield of foxtail millet [Setaria italica (L.)] genotypes. The experiment was laid on split plot design consisting of three genotypes in the main plot and seven different levels of micronutrients application in sub plot. The genotypes recorded non-significant difference with respect to the growth parameters and yield. Among the micronutrients application the treatment M₇: RDF + Soil application of ZnSO₄ at 15 kg ha^-1 and FeSO₄ at 10 kg ha^-1 + Foliar application of 0.5% ZnSO₄ and FeSO₄ each 30 DAS recorded significantly higher number of tillers plant^-1 (4.21), leaf area (41.26, 83.47 and 27.82 cm² plant^-1 at 30, 60 and at harvest, respectively), total dry matter accumulation (2.53, 11.01 and 29.69 g plant^-1 at 30, 60 and at harvest, respectively), grain yield (2272 kg ha^-1), stover yield (9298 kg ha^-1) and harvest index (19.63 %). In interaction effect G₃: Sia-2644 and M₇: RDF + Soil application of ZnSO₄ @ 15 kg ha^-1 & FeSO₄ @ 10 kg ha^-1 + Foliar application of 0.5% ZnSO₄ and FeSO₄ each 30 DAS recorded significantly higher number of tillers plant^-1 (4.32), leaf area (41.75, 85.23 and 30.19 cm² plant^-1 at 30, 60 and at harvest, respectively), total dry matter accumulation (2.48, 11.28 and 30.52 g plant^-1 at 30, 60 and at harvest, respectively), grain yield (2321 kg ha^-1), stover yield (9363 kg ha^-1) and harvest index (19.85 %).
