Sathiyavarsha K · Answer

1. Nutrient Deficiency
Nutrient	Deficiency Symptoms	Effect on Flowers/Fruits
Nitrogen (N)	Yellowing leaves, weak new growth	Fewer flowers/fruits, weak plant growth
Phosphorus (P)	Poor flowering, small or undeveloped fruits	Delayed fruiting, low flower set
Potassium (K)	Flower drop, small and irregular fruits	Reduced fruit number and size
Calcium (Ca)	Death of young leaves and flowers, tip burn	Poor fruit quality, early flower drop
Magnesium (Mg)	Interveinal yellowing of leaves	Reduced flowering and poor fruit color
Zinc (Zn)	Small flowers, irregular flower formation	Smaller fruits, poor yield
2. Water Deficiency or Improper Irrigation

Lack of water causes flowers to drop early and fruits to remain small.

Excess water can cause flowers to rot and fruits to split.

3. Light and Temperature

Insufficient sunlight reduces flowering.

Extreme heat or cold can cause flower and fruit drop.

4. Other Causes

Pests and diseases: Fruit borers, aphids, or fungal infections can cause flower/fruit drop.

Seasonal changes: Sudden temperature fluctuations can lead to flower and fruit drop.

Improper pruning: Excessive pruning may reduce flower and fruit formation.

Remedies

Provide balanced nutrients including NPK and micronutrients like Zn, Mg, and Ca.

Maintain proper irrigation; avoid water stress or waterlogging.

Control pests and diseases using appropriate pesticides or fungicides.

Ensure correct pruning and proper flower/fruit setting.

Use mulching and organic manure to improve soil fertility.
