Micronutrients in Banana
Balanced micronutrition is important in the banana crop and applications need to take into account complete crop needs at any stage of development. Critical leaf tissue values are given below.

Trials show that where supplies of boron, copper, iron, manganese, molybdenum and zinc are insufficient, plant growth, productive leaf area and yield suffers. This applies equally to plantains as well as bananas.
Boron, copper, iron and zinc also influence fruit quality, helping to boost TSS levels in the pulp.
