Role of Iron in Tomato Production

Iron is required for nitrate and sulfate reduction and is associated with chlorophyll formation and photosynthesis.

Iron and yield

In deficient soils, basal dressings of ferrous sulfate at the vegetative stage proved to be the most effective means of improving crop yields.

General guidelines for iron application

Leaves require at least 60 mg/kg of iron prior to flowering to fuel growth. Applications of iron (e.g. as foliar or through fertigation) can be used to increase early leaf production and crop productivity. As much as 60-300mg/kg are required prior to flowering to fuel growth.
