The correct answer is: A) Drip irrigation
Drip irrigation is a type of irrigation that delivers water directly to the root zone of plants, either through drippers or micro-sprinklers. It is a very efficient way to irrigate, as it minimizes water loss due to evaporation and runoff. Drip irrigation is also very effective in reducing soil erosion and nutrient leaching.
Canal irrigation is a type of irrigation that uses canals to transport water from a source, such as a river or lake, to fields. Canal irrigation is a very old method of irrigation, and it is still widely used in many parts of the world. However, canal irrigation can be inefficient, as water can be lost through evaporation and seepage.
Well irrigation is a type of irrigation that uses wells to extract water from the ground. Well irrigation is a very common method of irrigation in many parts of the world, including India. Well irrigation can be very efficient, as water can be delivered directly to the root zone of plants. However, well irrigation can be expensive, as it requires the construction of wells and pumps.
Sprinkler irrigation is a type of irrigation that uses sprinklers to spray water onto crops. Sprinkler irrigation is a very common method of irrigation in many parts of the world, including India. Sprinkler irrigation can be very efficient, as it can deliver water to a large area. However, sprinkler irrigation can be wasteful, as water can be lost through evaporation and runoff.
In Karnataka, drip irrigation is the most commonly used type of irrigation for horticultural crops. Drip irrigation is a very efficient way to irrigate, as it minimizes water loss due to evaporation and runoff. Drip irrigation is also very effective in reducing soil erosion and nutrient leaching.
