Subsistence farming and the crops grown:

Subsistence farming is a type of farming where the farmer grows crops primarily for the consumption of their own family or community, rather than for commercial purposes. It is characterized by small-scale agricultural practices, minimal use of modern technology, and limited surplus production. In subsistence farming, the main goal is to produce enough food to meet the immediate needs of the household.

The crops grown mostly under subsistence farming:

Among the given options, the crops that are grown mostly under subsistence farming are Millets and Rice. Let's understand why these are the preferred crops for subsistence farming:

1. Millets:
- Millets are small-seeded grains that are highly suitable for subsistence farming due to their resilience and adaptability to diverse climatic conditions. They can be grown in areas with low rainfall and poor soil fertility.
- Millets such as pearl millet, foxtail millet, and finger millet are staple food crops in many parts of India and Africa, where subsistence farming is prevalent.
- These crops require minimal inputs in terms of irrigation, fertilizers, and pesticides, making them cost-effective for small-scale farmers.
- Millets are highly nutritious and provide essential nutrients like carbohydrates, protein, fiber, vitamins, and minerals, making them an important food source for subsistence farmers.

2. Rice:
- Rice is a major staple crop in many parts of Asia, particularly in countries like India, China, and Indonesia. It is also a primary crop for subsistence farming in these regions.
- Rice cultivation requires a significant amount of water, making it suitable for areas with abundant rainfall or access to irrigation facilities.
- It is a high-calorie food crop and provides a good source of carbohydrates, which is crucial for subsistence farmers who rely on their own produce for sustenance.
- Rice can be stored for a longer duration, allowing subsistence farmers to have a steady food supply throughout the year.

In conclusion:

Millets and rice are the crops that are predominantly grown under subsistence farming. These crops are well-suited for small-scale farmers due to their resilience, adaptability, nutritional value, and relatively low input requirements. They play a vital role in ensuring food security and sustenance for subsistence farming communities.
