In India, which of the following means of irrigation, irrigates maximum area?

Question

Accepted Answer

In India, Wells and Tubewells irrigate the maximum area. Here's why:

*   **Why Wells and Tubewells (Option 3) are correct:** Wells and tubewells provide a readily accessible and controllable source of irrigation water for individual farmers. This decentralized nature allows for widespread adoption across diverse geographical regions and cropping patterns. The flexibility and ease of use of wells and tubewells, coupled with government subsidies and technological advancements in drilling and pumping, have led to their extensive use, making them the dominant source of irrigation in India. Data consistently shows that wells and tubewells account for the largest share of irrigated land in the country.

*   **Why Canals (Option 1) are incorrect:** While canals are a significant source of irrigation, their reach is limited by topography and the availability of perennial rivers. Canal irrigation requires large-scale infrastructure projects and is often concentrated in specific regions. The efficiency of canal irrigation can also be affected by water losses due to seepage and evaporation. Therefore, canals, while important, do not irrigate as much area as wells and tubewells nationwide.

*   **Why Tanks (Option 2) are incorrect:** Tanks are a traditional form of irrigation, particularly important in peninsular India. However, their capacity is limited by rainfall patterns and the size of the catchment area. Many tanks have also fallen into disrepair or have been encroached upon. While tanks play a crucial role in local irrigation, their overall contribution to the total irrigated area in India is significantly less than that of wells and tubewells.

*   **Why Canal and Tanks (Option 4) are incorrect:** This option combines two sources of irrigation that, while important, individually and collectively do not irrigate as much area as wells and tubewells. The limitations of canals and tanks, as described above, prevent them from irrigating the maximum area in India.
