Role of Zinc in Tomato Production

Zinc is involved in a range of enzyme reactions similar to manganese and magnesium. It is important for the development and function of growth regulators (e.g. auxin) that influence internode elongation. It is also involved in chloroplast development.

General guidelines for zinc application

Zinc can be applied throughout the season. Applications should ensure sufficient zinc is available prior to flowering. Foliar applications are the most appropriate means of treating a deficiency. Deficiencies occur only rarely in greenhouse crops.

Zinc at tomato growth stages 
Establishment Ensures good shoot growth
Vegetative growth Ensures growth is not limiting
Flowering - fruit set Maximizes flower set, development and fruiting
Fruit ripening - maturity Ensures even ripening
