Geographical conditions for the rice cultivation:
- Temperature: 16°C – 27°C
- Rainfall: 100 cm to 200 cm
- Soil: rice is grown well on the alluvial soil or on the fertile river basins
- Land: Plain lands or gentle slopes are suitable for the production of rice
In the areas of less rainfall, it grows with the help of irrigation. Rice is grown in the plains of north and north-eastern India, coastal areas and the deltaic regions.

Introduction:
Rice is the crop that grows in alluvial soil and requires a rainfall of 150 cm. Alluvial soil is formed by the deposition of sediments brought by rivers and is characterized by its fertility and high water-holding capacity. Rice is a staple crop in many countries and is well-suited to grow in alluvial soil due to its specific water requirements.
Explanation:
Here is a detailed explanation of why rice is the correct answer:
1. Alluvial soil:
Alluvial soil is formed by the deposition of sediments carried by rivers. It is rich in organic matter, minerals, and nutrients, making it highly fertile. Alluvial soil is well-drained and has a good water-holding capacity, making it suitable for growing a variety of crops.
2. Water requirement:
Rice is a semi-aquatic crop that requires a significant amount of water for its growth and development. It is typically grown in areas with abundant rainfall or in regions with access to irrigation facilities. The water requirement of rice is around 150 cm, which means it needs a consistent supply of water throughout its growing season.
3. Adaptation to alluvial soil:
Rice has adapted well to alluvial soil due to its unique water requirements. Alluvial soil's high water-holding capacity ensures that the rice plants have access to sufficient moisture for their growth. The soil's fertility provides the necessary nutrients for the crop to thrive.
4. Other crops:
While other crops like wheat, groundnut, and sugarcane can also grow in alluvial soil, they may have different water requirements. Wheat, for example, requires less rainfall and can be grown in different soil types. Groundnut prefers well-drained soil and can tolerate a range of rainfall conditions. Sugarcane requires a significant amount of water but can be grown in various soil types.
Conclusion:
In conclusion, rice is the crop that grows in alluvial soil and requires 150 cm of rainfall. Its adaptation to alluvial soil and specific water requirements make it a suitable choice for cultivation in regions with this type of soil.
