3. Powerloom irrigation
4. Drip irrigation

Answer 1

Correct Answer - Option 4 : Drip irrigation

Explanation:

Drip irrigation has the highest irrigation efficiency.

• Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants.
• Either from above the soil surface or buried below the surface.
• The goal is to place water directly into the root zone and minimize evaporation.
• Drip irrigation is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates (2-20 liters/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or drippers.
• With drip irrigation water, applications are more frequent (usually every 1-3 days) than with other methods and thus provides a very favorable high moisture level in the soil in which plants can flourish.
