Question

Explain how the type of crops grown determines the need for irrigation.

Answer 1

1. Water Requirements of Crops: Different crops have varying water needs. For instance, rice and sugarcane are water-intensive and require frequent and abundant irrigation, while millets and pulses need less water and can thrive with limited irrigation.
2. Growing Seasons: Crops grown in dry or non-monsoon seasons (like rabi crops such as wheat and mustard) rely heavily on irrigation since natural rainfall is insufficient during these periods.
3. Soil Moisture Sensitivity: Some crops, like vegetables and fruits, are highly sensitive to changes in soil moisture. These crops need a consistent and controlled water supply to maintain yield and quality, increasing the dependence on irrigation.
4. High-Yield Varieties (HYVs): Modern HYVs used in intensive farming demand more water to realize their full production potential. These crops necessitate assured irrigation to avoid stress and ensure productivity.
