Citrus is the largest fruit crop grown in Pakistan and Kinnow is the major planted species. About 94% of the total citrus is produced in the Punjab province (Sharif et al., 2005). Macro- and micro-nutrient deficiencies have been reported in citrus orchards of Punjab (Rashid et al., 1994). These deficiencies are usually recognized by distinctive symptoms that appear on the leaves and sometimes on fruits, branches or general growth of the tree (Ibrahim et al., 2007).
