Abstract: A field experiment entitled “Effect of zinc and iron fertilization on yield of groundnut (Arachis hypogaea L.) Under dryland condition†was conducted at Main Dry Farming Research Station, Junagadh Agricultural University, Targhadia during kharif season of 2017. The experiment comprising ten treatments viz., T 1 (control), T 2 (RDF), T 3 (RDF + 10 kg ZnSO 4 ha -1), T 4 (RDF + 15 kg FeSO 4 ha -1), T 5 (RDF + 10 kg ZnSO 4 ha -1 + 15 kg FeSO 4 ha -1), T 6 (RDF + spray of 1 % ZnSO 4 at 30 and 45 DAS), T 7 (RDF + spray of 1 % FeSO 4 at 30 and 45 DAS), T 8 (RDF + spray of 1 % ZnSO 4 + 1 % FeSO 4 at 30 and 45 DAS), T 9 (RDF + 5 kg ZnSO 4 ha -1 + 1 % ZnSO 4 spray at 30 and 45 DAS) and T 10 (RDF + 7.5 kg FeSO 4 ha -1 + 1 % FeSO 4 spray at 30 and 45 DAS). These treatments were laid out in RBD with four replications. The experiment was conducted on a clayey soil which was slightly alkaline in reaction with pH 8.11 and no saline (EC 0.32 dS m -1), medium in available nitrogen (276 kg ha -1), low in phosphorus (22.40 kg ha -1), high in potassium (463 kg ha -1), medium in sulphur (12.2 mg kg -1), high in iron (10.08 mg kg -1), medium zinc (0.58 mg kg -1). Groundnut variety ‘GG-20’ was sown in first week of July at a spacing of 60 x 10 cm using seed rate of 120 kg ha -1 and fertilizer application as per treatment. Significantly the higher pod (2527 kg ha -1) and haulm (5342 kg ha -1) yield of groundnut was recorded under combined application of RDF + spray of 1 % ZnSO 4 + 1 % FeSO 4 at 30 and 45 DAS, but it remained at par with individual application of zinc and iron as basal in soil alone or in combination as soil plus foliar application. Conversely, significantly the lowest pod and haulm yields were noted under control. Economical evaluation showed that the maximum gross realizations (122516 ha -1), net realization of (94957 ha -1) with B:C ratio of (4.45) was obtained from treatment spray of 1 % ZnSO 4 + 1 % FeSO 4 at 30 and 45 DAS besides the recommended dose of nitrogen and phosphorus and lowest remained over control. Based on the results of experimentation, it is concluded that the combined foliar application of 1 % ZnSO 4 + 1 % FeSO 4 at 30 and 45 DAS along with recommended dose of nitrogen and phosphorus (12.5:25 kg ha -1) in Kharif groundnut gave maximum production and higher net realization, apart from improving soil fertility under dryland condition.
