Which irrigation method is commonly used in regions with limited water resources?

  1. Flood irrigation

  2. Drip irrigation

  3. Sprinkler irrigation

  4. Furrow irrigation


Correct Option: B
Explanation:

Drip irrigation is a water-efficient irrigation method that delivers water directly to the root zone of plants, minimizing water loss due to evaporation and runoff.

What is the primary objective of agricultural water management?

  1. Maximizing crop yield

  2. Minimizing water usage

  3. Preventing soil erosion

  4. Controlling pests and diseases


Correct Option:
Explanation:

Agricultural water management aims to optimize crop production by providing adequate water for plant growth while minimizing water wastage and ensuring sustainable water use.

Which water conservation technique involves storing excess water during rainy seasons for use during dry periods?

  1. Rainwater harvesting

  2. Drought-tolerant crops

  3. Mulching

  4. Crop rotation


Correct Option: A
Explanation:

Rainwater harvesting is the process of collecting and storing rainwater for various purposes, including agricultural irrigation during dry periods.

What is the primary purpose of mulching in agricultural water management?

  1. Improving soil fertility

  2. Controlling weeds

  3. Reducing soil erosion

  4. Conserving soil moisture


Correct Option: D
Explanation:

Mulching helps conserve soil moisture by reducing evaporation from the soil surface, thereby improving water availability for plants.

Which irrigation method involves flooding the entire field with water?

  1. Furrow irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. Flood irrigation


Correct Option: D
Explanation:

Flood irrigation is a traditional irrigation method where water is applied to the entire field by flooding it, resulting in complete submergence of the crop.

What is the role of crop rotation in agricultural water management?

  1. Improving soil fertility

  2. Controlling pests and diseases

  3. Reducing water usage

  4. Preventing soil erosion


Correct Option:
Explanation:

Crop rotation involves growing different crops in sequence on the same land, which helps improve soil fertility, control pests and diseases, reduce water usage, and prevent soil erosion.

Which irrigation method involves distributing water through a network of pipes and sprinklers?

  1. Furrow irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. Flood irrigation


Correct Option: B
Explanation:

Sprinkler irrigation involves distributing water through a network of pipes and sprinklers, creating a rain-like effect over the field.

What is the primary purpose of contour farming in agricultural water management?

  1. Improving soil fertility

  2. Controlling soil erosion

  3. Increasing crop yield

  4. Reducing water usage


Correct Option: B
Explanation:

Contour farming involves farming along the contours of the land, which helps control soil erosion by reducing the speed of water runoff.

Which irrigation method involves creating furrows or channels in the field to distribute water?

  1. Furrow irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. Flood irrigation


Correct Option: A
Explanation:

Furrow irrigation involves creating furrows or channels in the field to distribute water, allowing it to flow along the furrows and reach the plant roots.

What is the primary purpose of terracing in agricultural water management?

  1. Improving soil fertility

  2. Controlling soil erosion

  3. Increasing crop yield

  4. Reducing water usage


Correct Option: B
Explanation:

Terracing involves constructing earthen embankments or ridges along the contours of the land to reduce the slope and control soil erosion.

Which irrigation method involves applying water directly to the root zone of plants?

  1. Furrow irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. Flood irrigation


Correct Option: C
Explanation:

Drip irrigation involves applying water directly to the root zone of plants through a network of emitters or drippers, minimizing water loss due to evaporation and runoff.

What is the primary purpose of irrigation scheduling in agricultural water management?

  1. Improving soil fertility

  2. Controlling soil erosion

  3. Optimizing water usage

  4. Preventing pests and diseases


Correct Option: C
Explanation:

Irrigation scheduling involves determining the frequency and amount of water to be applied to crops, aiming to optimize water usage and prevent over-irrigation or under-irrigation.

Which irrigation method involves applying water to the field using a moving sprinkler system?

  1. Furrow irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. Flood irrigation


Correct Option: B
Explanation:

Sprinkler irrigation involves applying water to the field using a moving sprinkler system, which distributes water in a uniform pattern over the field.

What is the primary purpose of using drought-tolerant crops in agricultural water management?

  1. Improving soil fertility

  2. Controlling soil erosion

  3. Reducing water usage

  4. Preventing pests and diseases


Correct Option: C
Explanation:

Drought-tolerant crops require less water to grow and can withstand dry conditions, making them suitable for regions with limited water resources.

Which irrigation method involves applying water to the field through a network of perforated pipes buried underground?

  1. Furrow irrigation

  2. Sprinkler irrigation

  3. Drip irrigation

  4. Subsurface irrigation


Correct Option: D
Explanation:

Subsurface irrigation involves applying water to the field through a network of perforated pipes buried underground, allowing water to seep directly into the root zone of plants.
