Symptoms
Leaves remain small and turn pale green, starting with the oldest leaves first. The stems become thin, hard and fibrous. Flowers are more readily aborted, resulting in poor fruit set. Fruits are small, pale green and deformed, especially at the blossom end.
Reasons
Nitrogen deficiency vs. optimum.
Efficient correction only possible before flowering.Beyond this stage yield loss and fruit deformation irreversible.
Melons - Chlorosis

Nitrogen deficiency vs. optimum made worse by
Low or high pH soils
Sandy or light soils (leaching)
Low organic matter
Drought conditions
High rainfall (leaching) or heavy irrigation
Addition or high levels of non-decomposed organic matter/manure (eg straw)
Melon:
Apply Nitrabor at 2-5 grams per hill every 5 days starting from 15 days after sowing (DAS) or 5 days after transplanting (DAT) until crop is 55 DAT or 65 DAS.
