The correct answer is: A) Canal irrigation.
Canal irrigation is the most common type of irrigation in Karnataka, accounting for over 60% of the state’s irrigated area. Canal irrigation is a system of water distribution that uses canals to transport water from a source, such as a river or reservoir, to fields where it is used to irrigate crops. Canal irrigation is a relatively efficient and cost-effective way to irrigate large areas of land.
Well irrigation is the second most common type of irrigation in Karnataka, accounting for over 20% of the state’s irrigated area. Well irrigation is a system of water distribution that uses wells to extract groundwater from the earth and transport it to fields where it is used to irrigate crops. Well irrigation is a relatively efficient way to irrigate small areas of land, but it can be expensive to operate and maintain.
Tank irrigation is the third most common type of irrigation in Karnataka, accounting for over 10% of the state’s irrigated area. Tank irrigation is a system of water distribution that uses tanks to store rainwater and then release it to fields where it is used to irrigate crops. Tank irrigation is a relatively inexpensive way to irrigate small areas of land, but it is not always reliable, as rainfall can be erratic.
Drip irrigation is the least common type of irrigation in Karnataka, accounting for less than 10% of the state’s irrigated area. Drip irrigation is a system of water distribution that uses small pipes to deliver water directly to the roots of plants. Drip irrigation is a very efficient way to irrigate crops, but it can be expensive to install and maintain.
In conclusion, canal irrigation is the most common type of irrigation in Karnataka, accounting for over 60% of the state’s irrigated area. Canal irrigation is a system of water distribution that uses canals to transport water from a source, such as a river or reservoir, to fields where it is used to irrigate crops. Canal irrigation is a relatively efficient and cost-effective way to irrigate large areas of land.
