When a system of open-jointed drains is artificially laid below the soil, so as to supply water to the crops by capillarity, then it is known as artificial sub-irrigation.
It may be recommended only in some special cases with favorable soil conditions and for cash crops of high return.

Sub irrigation is the correct answer.
Explanation:
Sub irrigation is a method of irrigation where water is delivered to the field through underground ditches or pipes. This technique is also known as subsurface irrigation or seepage irrigation. In sub irrigation, the water is distributed beneath the surface of the soil, allowing it to be absorbed by the roots of the plants through capillary action.
Advantages of Sub Irrigation:
- Efficient Water Use: Sub irrigation reduces water loss due to evaporation and runoff, as the water is delivered directly to the root zone of the plants.
- Reduced Weed Growth: Since the water is delivered underground, there is less moisture on the surface, which helps to suppress weed growth.
- Reduced Disease and Pest Problems: Sub irrigation minimizes the wetting of the plant foliage, reducing the risk of disease and pest infestations.
- Improved Nutrient Uptake: With sub irrigation, nutrients can be delivered directly to the root zone, promoting better nutrient uptake by the plants.
- Reduced Labor and Maintenance: Once the sub irrigation system is installed, it requires less labor and maintenance compared to other irrigation methods.
Comparison with Other Irrigation Methods:
- Trickle Irrigation: Trickle irrigation, also known as drip irrigation, involves delivering water directly to the root zone through emitters or drippers. While both sub irrigation and trickle irrigation deliver water directly to the root zone, sub irrigation is typically done below the soil surface, while trickle irrigation is done on the soil surface or below the plant canopy.
- Furrow Irrigation: Furrow irrigation involves delivering water to the field through small channels or furrows. This method is not as efficient as sub irrigation as it suffers from water loss due to evaporation and runoff.
- Border Irrigation: Border irrigation involves flooding the field with water through border ditches. This method is not as efficient as sub irrigation as it also suffers from water loss due to evaporation and runoff.
Conclusion:
Sub irrigation is a method of irrigation that delivers water underground to the root zone of the plants. This technique offers several advantages, including efficient water use, reduced weed growth, and improved nutrient uptake. It is a suitable method for maintaining the water table at the desired height for crops to access water through the capillary fringe.
