Field experiment was conducted to evaluate response of micronutrient on growth and yield of sweet sorghum at Instructional Dairy Farm, G.B.P.U.A. & T., Pantnagar, U.S.Nagar, Uttarakhand during Kharif seasons of 2012 and 2013. The soil of experimental site was silty clay loam having 7.7 pH, 0.81 % organic carbon, 273.35, 25.69 and 240 kg/ha available N, P and K respectively. The experiment was laid out in Randomized Block Design with 3 replications and ten treatments consisted of control, NPK 120:60:40 kg/ha (RDF), RDF+ZnSO4 25 kg/ha, RDF+FeSO4 25 kg/ha, RDF+0.2% ZnSO4 spray at 15 and 30 DAS, RDF+0.4% FeSO4 spray at 15 and30 DAS, RDF+0.2% ZnSO4+0.4% FeSO4 spray at 15 and 30 DAS, RDF+ZnSO4 15 kg/ha+0.2% ZnSO4 spray at 15 and 30 DAS, RDF+FeSO4 15 kg/ha+0.4% FeS04 spray at 15 and 30 DAS and RDF+ ZnSO4 15 kg/ha+FeSO4 15 kg/ha as soil application. RDF (NPK 120:60:40 kg/ha) in combination with ZnSO4 15 kg/ha + FeSO4 15 kg/ha as soil application showed maximum growth attributes characters (plant height, L:S, stem diameter), dry matter content, crude protein content, green fodder yield of 613.36 and 624.63 q/ha, dry fodder yield of 170.39, 177.21 q/ha as well as crude protein yield 16.65 and 17.44 q/ha, net and B:C ratio during 2012 and 2013, respectively followed by RDF+ZnSO4 25 kg/ha.
