Question

Most limiting factor for crop cultivation in desert areas is

• A. Water only
• B. Temperature only
• C. Water and Temperature
• D. Solar-radiation

Hint:

Desert agriculture:
- Limited by water scarcity and high temperature.
- Requires irrigation and heat-tolerant crops.
- Drip irrigation is often used.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question tests knowledge of limiting factors for crop cultivation in desert areas.

Step 2: Detailed Explanation:
In desert areas, the most limiting factors for crop cultivation are water and temperature (C).
- Water: Desert areas receive low rainfall (aridity).
- Temperature: High temperatures during the day cause heat stress.
Both water and temperature limit crop growth.
Other factors:
- Solar-radiation (D): Desert areas have high solar radiation, which is not a limiting factor.
Thus, water and temperature are the most limiting factors.

Step 3: Final Answer:
Thus, the most limiting factors are water and temperature, which corresponds to option (C).
