Role of Zinc in Melon Production
Zinc is involved in a range of enzyme reactions for energy production.
It is important for the development and function of growth regulators (e.g. auxin) that influence stem elongation and leaf expansion.
Zinc effect at growth stages
| Stage | Zinc effect |
| Pre-Planting | Ensure good shoot growth |
| Vegetative Growth | Ensure good leaf quality and that growth is not limiting |
| Flowering | Maximize flower set, development and fruiting |
| Fruit Fill | Promote healthy fruit-fill |

Zinc deficiencies in melon
New growth is adversely affected with internodes shortened and leaf size reduced. The new leaves are compressed into a rosette shape. Older leaves show initially yellowish-green interveinal chlorosis which later turns yellow or yellowish-white. The veins initially retain their green borders. The chlorosis is not as uniform as with manganese deficiency. Few flowers form and they are often sterile. Crop maturity is delayed.
