Answer ( Option C)

Artificial sub-irrigation

प्राकृतिक उप-सिंचाई

Solution

It is a system in which open joint drains is artificially laid below the soil, to supply water to the soil by capillarity. So, therefore it is very costly and can only be practiced in special cases, like favorable soil conditions and for cash crops of good return.
Artificial sub-irrigation is a device where open joint drains are mechanically placed under the ground to provide the soil with water by capillarity.
 
It is also very expensive and can only be done in exceptional situations, such as ideal soil conditions and a good return for cash crops.
Sub-irrigation is an irrigation system by which water is applied to the root zone of the plant.
 
In growing field crops such as tomatoes, peppers and sugar cane, sub-irrigation is used in areas with elevated water levels, such as Florida, and in industrial greenhouse operations.
