What is the primary goal of sustainable agriculture?

  1. Maximizing crop yields

  2. Reducing the use of chemical inputs

  3. Conserving soil and water resources

  4. Increasing profits for farmers


Correct Option: C
Explanation:

Sustainable agriculture prioritizes the preservation of soil health, water quality, and biodiversity, ensuring the long-term viability of agricultural systems.

Which of the following is a key principle of sustainable agriculture?

  1. Minimizing soil erosion

  2. Using synthetic fertilizers and pesticides

  3. Intensive irrigation practices

  4. Clearing forests for agricultural land


Correct Option: A
Explanation:

Sustainable agriculture aims to minimize soil erosion, which can lead to soil degradation and loss of fertility.

How does crop rotation contribute to sustainable agriculture?

  1. It reduces the need for chemical fertilizers

  2. It helps control pests and diseases

  3. It improves soil structure and fertility

  4. All of the above


Correct Option: D
Explanation:

Crop rotation offers multiple benefits, including reducing the reliance on chemical inputs, controlling pests and diseases, and enhancing soil health.

Which soil conservation practice involves planting vegetation along contours to slow down water runoff?

  1. Strip cropping

  2. Contour plowing

  3. Terracing

  4. Mulching


Correct Option: B
Explanation:

Contour plowing is a soil conservation technique that follows the natural contours of the land to reduce water runoff and soil erosion.

What is the purpose of using cover crops in sustainable agriculture?

  1. To suppress weed growth

  2. To improve soil structure

  3. To attract beneficial insects

  4. All of the above


Correct Option: D
Explanation:

Cover crops serve multiple purposes, including suppressing weeds, improving soil structure, and attracting beneficial insects that support a healthy ecosystem.

How does no-till farming contribute to soil conservation?

  1. It reduces soil erosion

  2. It improves soil moisture retention

  3. It enhances soil biodiversity

  4. All of the above


Correct Option: D
Explanation:

No-till farming minimizes soil disturbance, leading to reduced erosion, improved moisture retention, and enhanced soil biodiversity.

Which of the following is a sustainable pest management strategy?

  1. Using broad-spectrum pesticides

  2. Releasing beneficial insects

  3. Applying synthetic herbicides

  4. Burning crop residues


Correct Option: B
Explanation:

Releasing beneficial insects is a sustainable pest management strategy that utilizes natural predators to control pests, reducing the need for chemical pesticides.

What is the significance of maintaining soil organic matter in sustainable agriculture?

  1. It enhances soil fertility

  2. It improves soil structure

  3. It increases water-holding capacity

  4. All of the above


Correct Option: D
Explanation:

Maintaining soil organic matter is crucial as it improves soil fertility, structure, and water-holding capacity, leading to healthier and more productive soils.

How does integrated pest management (IPM) contribute to sustainable agriculture?

  1. It reduces the reliance on chemical pesticides

  2. It promotes biodiversity in agricultural systems

  3. It minimizes environmental pollution

  4. All of the above


Correct Option: D
Explanation:

Integrated pest management (IPM) combines multiple pest control methods to reduce the reliance on chemical pesticides, promote biodiversity, and minimize environmental pollution.

Which soil conservation practice involves constructing earthen embankments along contours to slow down water runoff?

  1. Strip cropping

  2. Contour plowing

  3. Terracing

  4. Mulching


Correct Option: C
Explanation:

Terracing is a soil conservation technique that involves constructing earthen embankments along contours to reduce water runoff and soil erosion.

What is the primary benefit of using drip irrigation in sustainable agriculture?

  1. It reduces water usage

  2. It minimizes soil erosion

  3. It prevents the growth of weeds

  4. It enhances soil fertility


Correct Option: A
Explanation:

Drip irrigation is a water-efficient irrigation method that delivers water directly to the plant roots, reducing water usage and minimizing evaporation losses.

How does mulching contribute to soil conservation and sustainable agriculture?

  1. It suppresses weed growth

  2. It conserves soil moisture

  3. It improves soil structure

  4. All of the above


Correct Option: D
Explanation:

Mulching offers multiple benefits, including suppressing weed growth, conserving soil moisture, improving soil structure, and reducing soil erosion.

Which of the following is a key indicator of soil health in sustainable agriculture?

  1. High levels of chemical fertilizers

  2. Presence of earthworms and beneficial microorganisms

  3. Absence of soil erosion

  4. Low soil organic matter content


Correct Option: B
Explanation:

The presence of earthworms and beneficial microorganisms in the soil is a key indicator of soil health and a thriving ecosystem.

What is the purpose of using green manure crops in sustainable agriculture?

  1. To improve soil fertility

  2. To control soil erosion

  3. To attract pollinators

  4. All of the above


Correct Option: D
Explanation:

Green manure crops serve multiple purposes, including improving soil fertility, controlling soil erosion, and attracting pollinators, supporting a healthy agricultural ecosystem.

How does crop diversification contribute to sustainable agriculture?

  1. It reduces the risk of crop failure

  2. It enhances soil biodiversity

  3. It minimizes the need for chemical inputs

  4. All of the above


Correct Option: D
Explanation:

Crop diversification offers multiple benefits, including reducing the risk of crop failure, enhancing soil biodiversity, and minimizing the need for chemical inputs.
