Question

______ irrigation makes the most liberal use of water.

Options

• Furrow

• Sprinkler

• Spray

• Drip

Answer 1

Furrow irrigation makes the most liberal use of water.

Explanation:

Furrow irrigation is a traditional surface method where large quantities of water are permitted to flow freely along parallel canals between crop rows, resulting in significant consumption. This unrestrained gravity flow causes significant water loss through deep soil seepage and surface evaporation, making it significantly less efficient than carefully controlled, water-saving approaches such as spray or drip irrigation.
