Which of the following is a type of sustainable agriculture that aims to minimize environmental impact and promote biodiversity?

  1. Conventional Agriculture

  2. Organic Agriculture

  3. Permaculture

  4. Intensive Agriculture


Correct Option: B
Explanation:

Organic agriculture emphasizes the use of natural methods and materials to promote soil health, reduce chemical inputs, and protect biodiversity.

What is the primary purpose of crop rotation in agricultural systems?

  1. To increase soil fertility

  2. To control pests and diseases

  3. To improve water conservation

  4. To reduce labor requirements


Correct Option: A
Explanation:

Crop rotation helps maintain soil fertility by diversifying the types of crops grown and preventing the build-up of pests and diseases associated with continuous monoculture.

Which irrigation method involves flooding fields with water?

  1. Sprinkler Irrigation

  2. Drip Irrigation

  3. Furrow Irrigation

  4. Subsurface Irrigation


Correct Option: C
Explanation:

Furrow irrigation is a traditional method where water is directed into furrows created between crop rows, allowing it to flow and soak into the soil.

What is the primary goal of sustainable agriculture?

  1. Maximizing crop yields

  2. Minimizing environmental impact

  3. Reducing labor costs

  4. Increasing profits


Correct Option: B
Explanation:

Sustainable agriculture prioritizes practices that minimize environmental impact, such as reducing chemical inputs, conserving water, and promoting biodiversity.

Which agricultural practice involves planting different crops in alternating rows or strips?

  1. Intercropping

  2. Monoculture

  3. Crop Rotation

  4. Contour Farming


Correct Option: A
Explanation:

Intercropping involves planting different crops in alternating rows or strips within the same field, promoting biodiversity and reducing the risk of pests and diseases.

What is the main purpose of contour farming?

  1. To improve soil drainage

  2. To reduce soil erosion

  3. To increase crop yields

  4. To facilitate irrigation


Correct Option: B
Explanation:

Contour farming involves plowing and planting along the contours of a slope, helping to reduce soil erosion caused by water runoff.

Which type of agriculture emphasizes the use of genetically modified organisms (GMOs)?

  1. Organic Agriculture

  2. Conventional Agriculture

  3. Sustainable Agriculture

  4. Permaculture


Correct Option: B
Explanation:

Conventional agriculture often utilizes genetically modified crops to enhance crop yields and resistance to pests and diseases.

What is the primary function of terraces in agricultural systems?

  1. To improve soil drainage

  2. To reduce soil erosion

  3. To increase crop yields

  4. To facilitate irrigation


Correct Option: B
Explanation:

Terraces are constructed on sloping land to reduce soil erosion by creating level areas for cultivation.

Which agricultural practice involves minimizing tillage to conserve soil and moisture?

  1. Conventional Tillage

  2. No-Till Farming

  3. Contour Farming

  4. Intercropping


Correct Option: B
Explanation:

No-till farming involves leaving crop residues on the field and planting directly into the soil, minimizing soil disturbance and conserving soil and moisture.

What is the primary purpose of crop diversification in agricultural systems?

  1. To increase soil fertility

  2. To control pests and diseases

  3. To reduce labor requirements

  4. To maximize crop yields


Correct Option: B
Explanation:

Crop diversification involves growing a variety of crops in the same area, helping to control pests and diseases by breaking their life cycles and reducing their populations.

Which agricultural practice involves planting trees or shrubs around crop fields?

  1. Contour Farming

  2. Agroforestry

  3. Intercropping

  4. Permaculture


Correct Option: B
Explanation:

Agroforestry involves integrating trees or shrubs into agricultural systems, providing various benefits such as soil conservation, improved water quality, and additional sources of income.

What is the main purpose of mulching in agricultural systems?

  1. To improve soil drainage

  2. To reduce soil erosion

  3. To suppress weed growth

  4. To increase soil temperature


Correct Option: C
Explanation:

Mulching involves covering the soil surface with organic materials, such as straw or compost, to suppress weed growth, conserve moisture, and improve soil health.

Which agricultural practice involves rotating livestock between different grazing areas?

  1. Contour Farming

  2. Agroforestry

  3. Rotational Grazing

  4. Permaculture


Correct Option: C
Explanation:

Rotational grazing involves moving livestock between different grazing areas on a regular basis, allowing pastures to recover and promoting sustainable grazing practices.

What is the primary purpose of cover crops in agricultural systems?

  1. To improve soil fertility

  2. To control pests and diseases

  3. To suppress weed growth

  4. To increase soil temperature


Correct Option: A
Explanation:

Cover crops are grown primarily to improve soil fertility by adding organic matter, fixing nitrogen, and preventing soil erosion.

Which agricultural practice involves using beneficial insects to control pests?

  1. Biological Control

  2. Chemical Control

  3. Mechanical Control

  4. Cultural Control


Correct Option: A
Explanation:

Biological control involves introducing beneficial insects or other organisms to prey on or parasitize pests, reducing their populations in a natural and sustainable manner.
