Abstract:

Micro-nutrients deficiencies are commonly prevail in low and lime-amended high fertility soils throughout the world. Keeping this in view, a field study was conducted to evaluate the efficacy of different zinc (Zn) sources (ZnSO 4 , 7H 2 O , ZnO 2 , Zn-EDTA and Zn-fulvate containing 22, 67.1, 14 and 8.3% Zn respectively) on growth, mineral contents and yield of three hybrid maize (FH-421, FH-810 and M-919). The results revealed that maize yield was significantly improved by Zn application. The data also showed that the biological yield, 1000- grain weight and grain yield was increased by 16, 7 and 23% respectively, over control in response to Zn- fulvate. It is concluded that Zn application as 12 kg Zn-fulvate ha–1 proved best in the agro-ecological conditions of Faisalabad, Pakistan.
