Which one of the following crops is not cultivated under dryland farming?
Sugarcane
Dryland farming refers to a set of agricultural techniques used to grow crops in arid or semi-arid regions where irrigation is not possible or practical. This type of farming relies entirely on natural rainfall. Therefore, crops suitable for dryland farming must be drought-tolerant and require relatively less water compared to crops grown in irrigated areas.
Let's analyze the given options in the context of dryland farming:
Based on the water requirements and drought tolerance of these crops, sugarcane stands out as the one least suitable for cultivation under dryland farming conditions. Jowar, Ragi, and Groundnut are relatively more drought-tolerant and are often grown in dryland regions.
| Crop | Typical Water Requirement | Suitability for Dryland Farming |
|---|---|---|
| Jowar (Sorghum) | Low to Moderate | Suitable (Drought-tolerant) |
| Ragi (Finger Millet) | Low | Highly Suitable (Very drought-tolerant) |
| Sugarcane | High | Not Suitable (Water-intensive) |
| Groundnut (Peanut) | Moderate | Suitable (Relatively drought-tolerant) |
Therefore, the crop that is not cultivated under dryland farming from the given options is Sugarcane due to its high water demand.
| Concept | Description |
|---|---|
| Dryland Farming | Farming without irrigation, relying solely on rainfall, typically in arid/semi-arid areas. |
| Drought Tolerance | Ability of a crop to survive and produce yield under conditions of water scarcity. |
| Water-intensive Crops | Crops that require large amounts of water for optimal growth and yield. |
Crops cultivated under dryland farming are often selected based on their ability to mature quickly, their efficient use of limited water resources, and their resilience to unpredictable rainfall patterns. Besides Jowar, Ragi, and Groundnut, other crops commonly grown in dryland areas include pulses (like pigeon pea, chickpea) and some oilseeds (like castor). Practices like water harvesting, soil moisture conservation, and selecting appropriate crop varieties are crucial for successful dryland agriculture.
