A field experiment was conducted during kharif, 2017 to study the fortification effect of zinc and iron on growth yield of sweet corn (Zea mays L.).The Growth parameters of sweet corn viz., plant height, leaf area index and dry matter production were influenced favourably with foliar application of 0.5 % ZnSO4 + 0.2 % FeSO4 at booting and silking along with RDF (N, P2O5 and K2O 180:60:50 kg ha-1). The yield and yield components viz., cob length, cob girth were significantly superior with 0.5 % foliar application of ZnSO4 + 0.2 % FeSO4 at booting and silking along with RDF (N, P2O5 and K2O 180:60:50 kg ha-1) (T10) compared to rest of the treatments. Lower growth and yield were observed with recommended dose of fertilizer alone.
