Under Cover Farming Quiz Quiz

Explore key concepts of polyhouse farming in horticulture, understanding its benefits, challenges, and core techniques for higher productivity. This easy quiz is ideal for learners interested in modern protected agriculture.

1. What is the main purpose of using a polyhouse in horticulture farming?

   Which key benefit does a polyhouse provide for growing crops such as tomatoes and capsicum?

   1. Forced pollination only
   2. Protection from adverse weather
   3. Increased need for chemical pesticides
   4. Reduced need for water entirely

   Explanation: The main purpose of polyhouse farming is to protect crops from adverse weather conditions, ensuring stable growth. Increased pesticide usage is not a benefit and is actually avoided in polyhouses. Water needs are managed, not eliminated. While controlled pollination can occur, it is not the primary benefit.

2. Which material is most commonly used to cover a polyhouse structure?

   Farmers constructing a polyhouse for vegetable cultivation often use which covering material?

   1. Glass tiles
   2. Cardboard panels
   3. Aluminum foil
   4. Polythene sheet

   Explanation: Polythene sheets are the most widely used material for covering polyhouses because they transmit light and are cost-effective. Aluminum foil and cardboard panels do not provide necessary transparency. Glass tiles are rare due to cost and fragility.

3. How does temperature regulation in a polyhouse benefit plant growth?

   In a polyhouse, which outcome is mainly achieved by maintaining optimal temperature for horticultural crops?

   1. Permanent soil sterility
   2. Faster and uniform crop growth
   3. Total elimination of irrigation
   4. Frequent plant disease outbreaks

   Explanation: Optimal temperature in a polyhouse supports faster and more uniform crop growth. Diseases may be reduced, not increased. Irrigation is still needed, though possibly reduced, and soil is managed to stay fertile, not sterile.

4. What irrigation method is commonly adopted in polyhouse cultivation of flowers and vegetables?

   Which irrigation system do polyhouse farmers frequently use to efficiently water their crops, such as roses or cucumbers?

   1. Rainfed irrigation
   2. Flood irrigation
   3. Sprinkler irrigation
   4. Drip irrigation

   Explanation: Drip irrigation is commonly chosen for polyhouses as it efficiently delivers water directly to plant roots and conserves water. Flood irrigation is too wasteful for controlled environments. Rainfed and sprinkler systems are less precise than drip systems.

5. Which of the following crops is especially suited for polyhouse farming due to controlled conditions?

   A farmer wishes to grow a high-value crop in a polyhouse; which crop is particularly suitable for this method?

   1. Capsicum (bell pepper)
   2. Wheat
   3. Sugarcane
   4. Rice

   Explanation: Capsicum is highly suitable for polyhouse farming because it requires controlled temperature and humidity, leading to better yield and quality. Staple crops like wheat, rice, and sugarcane are usually grown in open fields, not polyhouses.
