Agricultural Practices and Land Use Questions

Multiple choice general knowledge science & technology

Farmers can keep their soil fertile by--------

  1. Crop Rotation

  2. Regular Tilling

  3. Repeatedly growing the same crop

  4. Irrigation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Crop rotation maintains soil fertility by alternating different crops to prevent nutrient depletion and break pest cycles. Regular tilling can harm soil structure, growing the same crop repeatedly depletes specific nutrients, and irrigation alone doesn't maintain fertility.

  3. Crop Rotation

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Crop rotation alternates different crops seasonally to replenish soil nutrients and prevent depletion. Repeatedly growing the same crop drains specific nutrients from soil. While irrigation and tilling support plant growth, they don't maintain fertility like rotation does.

  2. Regular Tilling

  3. Irrigation

  4. Crop Rotation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Crop rotation prevents nutrient depletion by alternating different crops with varying nutrient needs, including legumes that fix nitrogen back into soil. Monoculture depletes specific nutrients, while excessive tilling disrupts beneficial soil structure and irrigation alone doesn't replenish nutrients.

  1. Regular Tilling

  2. Crop Rotation

  3. Repeatedly growing the same crop

  4. Irrigation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Crop rotation involves growing different crops in succession on the same land to prevent nutrient depletion and break pest/disease cycles. This maintains soil fertility naturally. Regular tilling can actually harm soil structure, repeatedly growing the same crop depletes specific nutrients, and irrigation provides water but does not maintain fertility.

  3. Crop Rotation

  4. Regular Tilling
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Crop rotation is the practice of growing different crops in the same area across different seasons. It maintains soil fertility by preventing nutrient depletion (different crops have different nutrient needs), breaking pest and disease cycles, and improving soil structure. Growing the same crop repeatedly depletes specific nutrients from the soil.

Multiple choice

Which of the following is not the advantage of mixed cropping?

  1. No risk of crop failure.

  2. Farmers can meet various requirements of family.

  3. Yield of both the crops increases.

  4. Less pest infection.

  5. Regular and reliable supply of water.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

It is the advantage of irrigation. Chances of pest infection is greatly reduced

Multiple choice

What are the characteristics of intercropping?

  1. Product of each crop can be marketed.

  2. Spraying of pesticides is difficult.

  3. Seeds of two crops are mixed before sowing.

  4. No set pattern of rows of crops.

  5. Its target is to minimise risk of crop failure.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Product of each crop can be marketed and consumed separately.

Multiple choice

How can we protect the crops?

  1. By using pesticides

  2. By using resistant varieties

  3. Implementing crop rotation

  4. Summer ploughing

  5. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Weeds, insect pests and disease-causing organisms can damage the crop. Thus, crops can be protected by all of the above mentioned methods.

Multiple choice

How is crop rotation beneficial?

  1. Helps in replenishment of soil fertility

  2. Prevents depletion of selective nutrients

  3. Enhances production

  4. All of the above

  5. Both 2 and 3
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Practice of growing different crops on a piece of land increases soil fertility, which enhances production and helps in maintaining the nutrient level.

Multiple choice

Which of the following is/are the benefit(s) of leveling of the ploughed soil?

a. Levelling helps in the loss of moisture from the ploughed soil. b. Levelling of ploughed fields prevents the top fertile soil from being eroded. c. Levelling of ploughed fields helps in the uniform distribution of water.

  1. only a

  2. only a and b

  3. only b and c

  4. only a and c

  5. a, b and c
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct option as all of the above are the benefits of levelling of the ploughed soil.

Multiple choice

Which of the following is not a benefit of loosening of soil by ploughing?

  1. The loosening and turning of soil during ploughing brings the nutrient-rich soil to the top.

  2. Ploughing uproots and buries the weeds standing in the fields.

  3. The loose soil allows deep penetration of water, which is otherwise not possible.

  4. The loose soil helps in the growth of worms and microbes present in the soil.

  5. The loose soil allows the roots of the plants to breathe easily.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is the correct option as this is not a benefit of loosening of soil by ploughing.
