Polyhouse Farming Kerala
What is Polyhouse Farming?
Polyhouse farming is a protected cultivation method where crops are grown inside a structure covered with transparent or semi-transparent material.
This controlled environment helps farmers manage temperature, humidity, pests, and water usage more efficiently.
Polyhouse farming in Kerala is used for:
- Vegetable cultivation
- Flower production
- Nursery raising
- High-value horticulture crops
- Off-season production
- Improved crop quality and yield
It is especially useful where weather conditions are unpredictable or where high-value crops need better protection.
Benefits
Benefits of polyhouse farming:
- Higher yield per unit area
- Better control over temperature and humidity
- Reduced pest and disease attack
- Off-season crop production
- Improved quality and uniformity of produce
- Better water and fertilizer efficiency
- Suitable for high-value crops
- Greater income potential compared to open-field farming
Polyhouse systems can help farmers earn more from a smaller area when managed properly.
