Question

Sustainable agriculture involves

• A. Mixed cropping
• B. Crop rotation
• C. Mixed farming
• D. All of the above

Answer 1

The correct option is D

All of the above

The correct option is D

The explanation for the correct option:

1. The mixed farming approach aids in lowering production costs per unit area, boosting income and productivity, and lowering farmer risk.
2. Mixed cropping, also known as intercropping, is the earliest form of systemized agricultural production, involving the simultaneous cultivation of two different species or cultivars of the same species on the same field.
3. Crop rotations can help the soil's physical, chemical, and biological characteristics improve or stay the same.

The explanation for the incorrect options:

Option A:

1. Because the fertilizer and water demands of plants in agriculture are diverse, there is less need for these inputs in mixed cropping.
2. Pests are naturally managed since their natural predators seek out a variety of environments to thrive.
3. When compared to monoculture, this method yields a significantly higher yield per hectare.

Option B:

1. Crop rotation helps to control insects and illnesses while also improving soil fertility and reducing soil erosion.
2. Multiple cropping occurs when two or three different crops are grown in succession on the same piece of land in the same year.

Option C:

1. Mixed farming, which involves combining crops and cattle in the same farming operation, provides the most variation.
2. Soil erosion can be reduced by growing crops solely on more level terrain and pastures or forages on steeper slopes.
3. In animal production systems, feeding and marketing are both adjustable. This can help farmers protect themselves from price changes and make better use of agricultural labor.

Final Answer: Sustainable agriculture involves Mixed cropping, mixed farming, and crop rotation
