The results showed that T3 (15 kg ZnSO4 ha1) treatment produced maximum paddy yield (3.80 t ha1) than all other treatments. This higher yield was attributed to increase number of fertile tillers m2 and greater harvest index in this treatment as compared to other treatments. It was concluded that application of ZnS04 at 15 kg ha1 at the time of puddling is the most economical to obtain higher yield under Faisalabad conditions.]]>Ahmad, S.,19881988Anonymous,19941994Awan, I.U., H.U.
