Option C: Controls pests and diseases
Option D: Requires more manual labor
Answer: Option C
View AnswerSolution:
- Crop rotation helps control pests and diseases by disrupting their life cycles.
- This practice enhances soil health and fertility by preventing nutrient depletion associated with continuous cropping of the same species.
- Crop rotation can also improve overall biodiversity on a farm, which is beneficial for the ecosystem.
Question 6:
Which type of crops are sown with the onset of the monsoon?
Option A: Rabi crops
Option B: Kharif crops
Option C: Cash crops
Option D: Food crops
Answer: Option B
View AnswerSolution:
- Kharif crops are sown with the onset of the monsoon and harvested at the end of the rainy season.
- Examples include paddy and maize, which thrive in the warm, wet conditions typical of this season.
- Interestingly, the timing of sowing these crops is crucial for maximizing yield, making it a vital practice in agriculture.
Question 7:
What is organic manure made from?
Option A: Synthetic chemicals
Option B: Decomposed organic matter
Option C: Mineral fertilizers
Option D: Pesticides
Answer: Option B
View AnswerSolution:
- Organic manure is derived from decomposed organic matter, such as animal excreta and plant waste.
- This natural fertilizer enhances soil fertility and promotes healthy plant growth.
- Organic manure improves soil structure and moisture retention, contributing to sustainable agriculture.
Manure
Question 8:
Which method is used to remove unwanted plants from a crop field?
Option A: Sowing
Option B: Threshing
Option C: Weeding
Option D: Plowing
Answer: Option C
View AnswerSolution:
- Weeding involves removing unwanted plants that compete with crops for resources.
- This can be done manually or with chemicals known as weedicides.
- Regular weeding is crucial for maximizing crop yields and minimizing competition for nutrients.
Question 9:
What happens if wheat is sown in the Kharif season?
Option A: The crop yields high returns
Option B: The crop fails due to unsuitable conditions
Option C: The crop matures faster
Option D: The crop requires less irrigation
Answer: Option B
View AnswerSolution:
- Wheat is not suitable for the Kharif season because it requires mild temperatures and frost-free conditions.
- Sowing wheat during this time can lead to poor yields due to high temperatures and excessive moisture.
- Interestingly, farmers need to be aware of seasonal changes to optimize their planting schedules for better crop success.
Question 10:
Which irrigation method mimics natural rainfall?
Option A: Drip irrigation
Option B: Surface irrigation
Option C: Sprinkler irrigation
Option D: Flood irrigation
Answer: Option C
View AnswerSolution:
- Sprinkler irrigation simulates natural rainfall by distributing water through pipes and nozzles.
- This method is beneficial for irrigating large areas and can be adjusted according to the crop's needs.
- A notable advantage is that well-designed sprinkler systems can significantly reduce water loss through evaporation, making them efficient for water conservation.

Question 11:
What is the main disadvantage of continuous cropping?
Option A: Increased soil fertility
Option B: Decreased crop diversity
Option C: Higher yields
Option D: Less need for irrigation
Answer: Option B
View AnswerSolution:
- Continuous cropping leads to decreased crop diversity, which can result in pest and disease problems and nutrient depletion in the soil.
- Crop rotation is often recommended as a solution to maintain soil health and improve biodiversity.
Question 12:
Which of the following statements about chemical fertilizers is true?
Option A: They are made from organic matter.
Option B: They are synthetic substances for plant growth.
Option C: They improve soil structure.
Option D: They are primarily used in organic farming.
Answer: Option B
View AnswerSolution:
- Chemical fertilizers are synthetic substances added to the soil to provide essential nutrients, helping boost crop yields.
