Which method has the highest water use efficiency

Correct option is C

Drip irrigation method supplies water directly to the root zone of plants in a slow and controlled manner, minimizing losses. Water application is highly precise, which reduces evaporation, runoff, and deep percolation losses significantly. This method ensures maximum utilization of applied water by crops, leading to the highest water use efficiency among irrigation methods.
Information booster: Drip irrigation is also known as trickle irrigation and is widely used in horticultural and plantation crops. It improves water productivity by supplying water in small quantities at frequent intervals according to crop demand. The method helps in efficient fertilizer application through fertigation, enhancing nutrient use efficiency. Drip irrigation is especially beneficial in water-scarce regions and under arid and semi-arid conditions.
Why other options are incorrect: (a) Sprinkler irrigation method has higher evaporation losses compared to drip irrigation. (b) Surface irrigation method results in uneven water distribution and large conveyance losses. (d) Basin irrigation method leads to excess water use and poor efficiency due to standing water.
