Here are 20 multiple-choice questions (MCQs) related to cropping systems, with answers and explanations. These cover concepts such as monocropping, crop rotation, mixed cropping, intercropping, relay cropping, and more:


Question 1:

What is the definition of monocropping in agriculture?

  • A. Growing only one crop on a piece of land year after year
  • B. Growing multiple crops on the same piece of land in a single growing season
  • C. Rotating different crops on the same piece of land
  • D. Planting crops in a sequence over a fixed period

Answer: A. Growing only one crop on a piece of land year after year
Explanation: Monocropping involves growing a single crop on the same land for consecutive years. It can deplete soil nutrients and increase pest and disease vulnerability.


Question 2:

Which of the following is a common disadvantage of monocropping?

  • A. Increased soil fertility
  • B. Increased susceptibility to pests and diseases
  • C. Improved water retention
  • D. Reduced soil erosion

Answer: B. Increased susceptibility to pests and diseases
Explanation: Continuous monocropping creates an environment for pests and diseases to thrive, as there’s no crop diversity to disrupt their life cycles.


Question 3:

What is the primary principle behind crop rotation?

  • A. Growing different crops in succession on a piece of land over a specific period
  • B. Growing multiple crops on the same piece of land at the same time
  • C. Growing crops in different sequences each year
  • D. Growing crops only during certain seasons

Answer: A. Growing different crops in succession on a piece of land over a specific period
Explanation: Crop rotation helps maintain soil health by alternating crops with different nutrient needs, reducing soil depletion and disease cycles.


Question 4:

Which of the following is a key principle of crop rotation?

  • A. Leguminous crops should follow non-leguminous crops
  • B. Non-exhaustive crops should follow exhaustive crops
  • C. Crops of the same family should be grown in succession
  • D. Crops with fibrous roots should follow those with taproots

Answer: A. Leguminous crops should follow non-leguminous crops
Explanation: Legumes fix nitrogen in the soil, which benefits subsequent non-leguminous crops, improving soil fertility.


Question 5:

What is mixed cropping?

  • A. Growing multiple crops on the same piece of land at the same time
  • B. Rotating different crops over a period of time
  • C. Growing only one crop on a piece of land
  • D. Growing different crops on separate plots in the same field

Answer: A. Growing multiple crops on the same piece of land at the same time
Explanation: Mixed cropping involves cultivating different crops simultaneously on the same field to optimize resources and reduce the risk of total crop failure.


Question 6:

What is intercropping?

  • A. Growing multiple crops in alternating rows or patterns within the same field
  • B. Growing a second crop on the same field immediately after the first crop is harvested
  • C. Growing different crops on different fields in the same farm
  • D. Rotating crops over a multi-year cycle

Answer: A. Growing multiple crops in alternating rows or patterns within the same field
Explanation: Intercropping optimizes space and resources, allowing crops with complementary growth habits to share the same field.


Question 7:

What is relay cropping?

  • A. Planting a second crop before the first crop is harvested
  • B. Planting multiple crops in the same field at the same time
  • C. Rotating crops over a fixed period
  • D. Growing different crops on separate plots in the same field

Answer: A. Planting a second crop before the first crop is harvested
Explanation: Relay cropping increases land use efficiency by starting a second crop while the first is still growing, leading to continuous production.


Question 8:

What is multistoried cropping?

  • A. Growing crops at different heights in the same field to maximize space
  • B. Rotating crops over a multi-year cycle
  • C. Growing different crops on separate plots in the same farm
  • D. Planting multiple crops in alternating rows or patterns

Answer: A. Growing crops at different heights in the same field to maximize space
Explanation: This system maximizes vertical space by growing taller crops alongside shorter crops, optimizing light and resource use.


Question 9:

What is sole cropping?

  • A. Growing only one crop on a piece of land during a specific period
  • B. Growing multiple crops in alternating rows or patterns
  • C. Growing crops at different heights in the same field
  • D. Planting a second crop before the first crop is harvested

Answer: A. Growing only one crop on a piece of land during a specific period
Explanation: Sole cropping refers to cultivating a single crop on a field during a specific period or season, without combining it with other crops.


Question 10:

What is sequence cropping?

  • A. Planting two or more crops in sequence on the same piece of land in a single year
  • B. Growing multiple crops on the same piece of land at the same time
  • C. Rotating different crops over a multi-year cycle
  • D. Planting a second crop before the first crop is harvested

Answer: A. Planting two or more crops in sequence on the same piece of land in a single year
Explanation: Sequence cropping maximizes land use by planting multiple crops sequentially in one year, increasing overall productivity.
