Correct option is C
The correct answer is (c) Crop rotation
The practice of growing different crops on the same piece of land in a planned sequential order is referred to as crop rotation. It is an agricultural technique used to maintain soil fertility, control pests and diseases, and improve crop yield. For example, growing legumes after cereals replenishes nitrogen in the soil.
Information Booster:
- Single crop: This involves cultivating only one type of crop on a piece of land at a time. It is not ideal for long-term soil fertility.
- Intercropping: This refers to growing two or more crops simultaneously on the same piece of land in a specific pattern (e.g., maize with beans).
- Crop rotation: A planned sequence of different crops is grown in successive seasons (e.g., cereals followed by legumes).
- Mixed farming: A farming system where both crops and livestock are raised together on the same farm.
Additional Knowledge:
- Advantages of Crop Rotation:
- Prevents soil exhaustion and degradation.
- Reduces the dependency on chemical fertilizers.
- Controls the buildup of crop-specific pests and diseases.
- Improves soil structure and organic matter.
- Example of Crop Rotation:
- Legumes → Cereals → Oilseeds → Fodder crops.
- Crop rotation has been a traditional practice in sustainable agriculture for centuries.
