Abstract: The various levels of ZnS04 included in the experiment were 0, 5, 10, 15 and 20 kg ha–1 applied at the time of pudding. The results showed that T3 (15 kg ZnSO4 ha–1) treatment produced maximum paddy yield (3.80 t ha–1) than all other treatments. This higher yield was attributed to increase number of fertile tillers m–2 and greater harvest index in this treatment as compared to other treatments. It was concluded that application of ZnS04 at 15 kg ha–1 at the time of puddling is the most economical to obtain higher yield under Faisalabad conditions.
