A field experiment was conducted during kharif, 2014 at S.V. Agricultural College Farm, Tirupati to findout the response of fodder maize to different soil and foliar applications of zinc. The twelve nutrient management practices consisted of RDF (120 kg N – 50 kg P2O5 – 40 kg K2O ha-1) without zinc and different combinations of soil and foliar applications of zinc were studied in a randomized block design with three replications. The results of the experiment revealed that among all the treatments, the maximum plant height (362.0 cm), leaf area index (4.972), leaf to stem ratio (0.304), dry matter production (6695 kg ha-1) and green fodder yield (424 q ha-1) were recorded with RDF + soil application of 50 kg ZnSO4 ha-1 along with foliar application of 0.2% ZnSO4 at 30 and 45 DAS (T12). All the above growth parameters and yield were statistically comparable with RDF + soil application of 50 kg ZnSO4 ha-1 along with foliar application of 0.2% ZnSO4 at 45 DAS (T11). Hence, it can be concluded that application of zinc had significant influence on the growth parameters and green fodder yield of fodder maize.
