Ferrous sulphate (FeSO4. 7H2O); contains 20 % iron.

Iron plays an important role in synthesis of chlorophyll which is essential for

photosynthetic activity. It is also required for chemical reduction of nitrate and

sulphate and in nitrogen assimilation.

2.4.2. Deficiency symptoms:

Rice: Interveinal chlorosis in streaks is noticed. Drying of leaves starts from

tips and margins. Under severe conditions, leaves become white and die.

Wheat: Deficiency of iron is manifested as interveinal chlorosis of upper most

leaves. As deficiency intensifies, leaves turn almost white and die.

Pulses: Yellowing of interveinal areas of young leaves is commonly noticed in

iron deficient plants. Severity leads to pale-white discoloration of leaves.

Dose and application method:

Ferrous sulphate is most commonly used source of iron. Soil application @ 50

kg/ha to rice, wheat or pulses every 3 years or 15 kg/ha every year is recommended. However, it is more effective when applied as foliar spray of 1 % solution, 2-3 times at weekly interval in rice, wheat or pulse crops.
