Sugarcane is an important cash crop which produces higher biomass and therefore its nutrient requirement is also high. Intensive cane cultivation and inadequate supply of organic matter has led to some micronutrient deficiency. Iron is an important micronutrient which aids in photosynthesis. The occurrence of iron chlorosis is very common in Tamil Nadu. Excessive calcium influences iron chlorosis and hence it is frequently noticed in calcarious soils and is referred as lime induced chlorosis. Application of ferrous sulphate as basal fertilizer or foliar spray leads to correction of iron deficiency and paved the way for increasing cane yield.
