Question

Define protected cultivation.

Hint:

Think of crops grown inside a greenhouse or polyhouse under controlled conditions.

Answer 1

Step 1: Understand the idea:
Crops normally grow in open fields, where weather cannot be controlled.
Heat, cold, heavy rain, wind, pests and disease can all damage the crop.

Step 2: Write the definition:
Protected cultivation is the growing of crops under a controlled or partly controlled environment.
The crop is grown inside structures that protect it from harsh weather, pests and diseases.

Step 3: Give examples:
Common structures are greenhouses, polyhouses, net houses, shade nets and low tunnels.
Flowers such as rose, carnation, gerbera and chrysanthemum are grown this way.

Final Answer:
Protected cultivation is growing crops inside structures such as a polyhouse or greenhouse, where temperature, light and humidity are controlled.
