Which of the following methods of irrigation is most efficient in terms of water conservation?
Answer Details
Of the given options, drip irrigation is the most efficient method of irrigation in terms of water conservation.
Drip irrigation involves the slow and steady release of water directly onto the roots of the plants. This method reduces water waste, as the water goes exactly where it is needed and minimizes evaporation. Additionally, because the water is delivered directly to the roots, there is less runoff and less chance of water being lost to erosion.
In comparison, flood irrigation involves flooding a field with water, which can lead to water loss through runoff and evaporation. Furrow irrigation and border irrigation are similar to flood irrigation in that they involve the flooding of fields, but they are less efficient than drip irrigation.
Therefore, for efficient water conservation, drip irrigation is the best method out of the given options.
