The correct answer is: A) Rainfed areas.
Mixed cropping is a farming practice in which two or more crops are grown together in the same field. This practice is common in Telangana’s rainfed areas because it helps to improve soil fertility, reduce the risk of crop failure, and increase crop yields.
In rainfed areas, the amount of rainfall is often unpredictable and can vary greatly from year to year. This can make it difficult to grow a single crop successfully, as the crop may not receive enough water during a dry season or may be damaged by excessive water during a wet season. Mixed cropping helps to mitigate these risks by providing a diversity of crops that can tolerate different levels of rainfall.
In addition, mixed cropping can help to improve soil fertility. The roots of different crops can grow in different layers of the soil, which helps to aerate the soil and bring nutrients to the surface. This can improve the growth of all of the crops in the field.
Finally, mixed cropping can help to increase crop yields. By planting two or more crops together, farmers can use the land more efficiently and produce more food. This is especially important in rainfed areas, where land is often scarce.
The other options are incorrect because:
- B) Irrigated canal command areas are areas that receive water from canals. In these areas, farmers can grow a variety of crops, including single crops.
- C) Coastal regions are areas that are close to the sea. The soil in these areas is often saline, which makes it difficult to grow crops.
- D) Hilly areas are areas that are characterized by steep slopes. The soil in these areas is often shallow and eroded, which makes it difficult to grow crops.
