Abstract: A field experiment was conducted during Kharif 2018 at College Farm, College of Agriculture, PJTSAU to evaluate the effect of various sources of zinc and iron on soil nutrient status in finger millet. This experiment was conducted with randomized block design with 14 treatments and replicated thrice. The results revealed that application of different Zinc and iron sources at different rates significantly influenced the soil nutrient status in finger millet.The highest available N, P, K was obtained in treatment receiving RDF (60:40:30 kg N,P₂O₅ and K₂O kg ha^-1) + foliar application of FeSO₄ @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF+ foliar application of Fe-humate twice at 30 and 60 DAS at all the growth stages of finger millet.The highest available Fe was obtained in treatment receiving RDF+ FeSO₄ @ 50 kg ha^-1 which was on par with RDF+ foliar application of FeSO₄ @ 0.5% twice at 30 and 60 DAS. The highest available Zn was obtained in treatment receiving RDF+ ZnSO₄ @ 50 kg ha^-1 which was on par with treatment receiving RDF+ ZnSO₄ @ 0.2% foliar spray twice at 30 and 60 DAS.
