Growth, yield and post-harvest soil available nutrients in sweet corn (Zea mays L.) as influenced by zinc and iron nutrition

Abstract

A field experiment was conducted during kharif, 2017 to study the Growth, Yield and Post-harvest soil available nutrients in Sweet corn (Zea mays L.) as Influenced by Zinc and Iron Nutrition. The Growth parameters of sweet corn viz., plant height, leaf area index and dry matter production were influenced favorably 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 green cob and fodder yield were produced 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) compared to rest of the treatments. Lower growth and yield were observed with recommended dose of fertilizer alone.
