Which of the following irrigation methods is characterized by the direct application of water to the root zone of plants, minimizing evaporation and water wastage?
- Flood irrigation
- Sprinkler irrigation
- Drip irrigation
- Furrow irrigation
Show answer
Answer: C. Drip irrigation
Drip irrigation delivers water directly to the plant's root system in small, controlled amounts, significantly reducing water loss through evaporation and runoff compared to other methods. This targets water where it's most needed, making it highly efficient.
In the context of irrigation, what does 'water use efficiency' primarily refer to?
- The total volume of water applied to a field
- The amount of water lost to evaporation
- The ratio of crop yield to the amount of water consumed by the crop
- The speed at which water is delivered to the field
Show answer
Answer: C. The ratio of crop yield to the amount of water consumed by the crop
Water use efficiency in agriculture is a measure of how effectively water is converted into biomass or yield. It quantifies the amount of product obtained per unit of water consumed, not just applied or lost.
The 'Kuhls' or 'Tankas' system, prevalent in some parts of Rajasthan, India, is a form of:
- Canal irrigation
- Rainwater harvesting and storage for irrigation
- Drip irrigation
- Sprinkler irrigation
Show answer
Answer: B. Rainwater harvesting and storage for irrigation
Kuhls and Tankas are traditional systems where rainwater is collected and stored in tanks or reservoirs, and this stored water is then used for irrigation during drier periods, showcasing rainwater harvesting for agricultural use.
Which irrigation system is often described as 'overhead irrigation'?
- Drip irrigation
- Furrow irrigation
- Sprinkler irrigation
- Subsurface irrigation
Show answer
Answer: C. Sprinkler irrigation
Sprinkler irrigation applies water from above the crop canopy, mimicking rainfall, hence it is often referred to as overhead irrigation.
Which of the following is a key advantage of drip irrigation for hilly or terraced agriculture?
- Requires extensive land leveling
- Minimizes soil erosion
- High water loss due to runoff
- Difficult to install on slopes
Show answer
Answer: B. Minimizes soil erosion
Drip irrigation applies water slowly and directly to the soil at the plant base, reducing surface water flow and thus minimizing soil erosion, which is a significant advantage on steep or terraced land.
