  3. To reduce soil erosion

  4. To increase crop yields

Show answer
Correct Option: A
Explanation:

Crop rotation helps control pests and diseases by disrupting their life cycles and reducing their populations.

Which of the following is not a benefit of crop rotation?

  1. Improved soil fertility

  2. Reduced soil erosion

  3. Increased crop yields

  4. Increased water usage

Show answer
Correct Option: D

Explanation:

Minimum tillage is a method of farming that uses less tillage than conventional tillage, but still some tillage.

What are the benefits of minimum tillage?

  1. Reduced soil erosion

  2. Improved soil structure

  3. Increased soil organic matter

  4. All of the above

Show answer
Correct Option: D
Explanation:

Minimum tillage has many benefits, including reduced soil erosion, improved soil structure, and increased soil organic matter.

What are some challenges of minimum tillage?

  1. Increased weed pressure

  2. Difficulty in incorporating crop residues

  3. Reduced nutrient availability

  4. All of the above

Show answer
Correct Option: D
Explanation:

Minimum tillage can present some challenges, such as increased weed pressure, difficulty in incorporating crop residues, and reduced nutrient availability.

Which of the following is not a type of crop rotation?

  1. Monoculture

  2. Double cropping

  3. Intercropping

  4. Strip cropping

Show answer
Correct Option: A
Explanation:

Monoculture is not a type of crop rotation because it involves growing the same crop year after year on the same land.

What is the most common type of crop rotation?

  1. Monoculture

  2. Double cropping

  3. Intercropping

  4. Strip cropping

Show answer
Correct Option: A
Explanation:

Monoculture is the most common type of crop rotation, although it is not recommended for sustainable agriculture.

What is the difference between crop rotation and intercropping?

  1. Crop rotation involves growing different crops on the same land in a sequence, while intercropping involves growing two or more crops together on the same land at the same time.

  2. Crop rotation involves growing different crops on the same land in a sequence, while intercropping involves growing two or more crops together on the same land in different seasons.

  3. Crop rotation involves growing different crops on the same land in a sequence, while intercropping involves growing two or more crops together on different land.

  4. Crop rotation involves growing different crops on the same land in a sequence, while intercropping involves growing two or more crops together on the same land in different years.

Show answer
Correct Option: A
Explanation:

Crop rotation involves growing different crops on the same land in a sequence, while intercropping involves growing two or more crops together on the same land at the same time.

What is the difference between crop rotation and strip cropping?

  1. Crop rotation involves growing different crops on the same land in a sequence, while strip cropping involves growing different crops on different strips of land.

  2. Crop rotation involves growing different crops on the same land in a sequence, while strip cropping involves growing different crops on different strips of land in different seasons.

  3. Crop rotation involves growing different crops on the same land in a sequence, while strip cropping involves growing different crops on different strips of land in different years.

  4. Crop rotation involves growing different crops on the same land in a sequence, while strip cropping involves growing different crops on different strips of land at the same time.

Show answer
Correct Option: A
Explanation:

Crop rotation involves growing different crops on the same land in a sequence, while strip cropping involves growing different crops on different strips of land.

What is the role of cover crops in crop rotation?

  1. To control pests and diseases

  2. To improve soil fertility

  3. To reduce soil erosion

  4. All of the above

Show answer
Correct Option: D
Explanation:

Cover crops can help control pests and diseases, improve soil fertility, and reduce soil erosion.

What is the role of no-till farming in minimum tillage?

  1. No-till farming is a type of minimum tillage that uses no tillage at all.
