2. Rain Gun
3. Drip irrigation
4. Ring Basin irrigation
5. None of the above

Answer 1

Correct Answer - Option 3 : Drip irrigation

The correct answer is Drip irrigation.

• Drip irrigation is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates from a system of small diameter plastic pipes fitted with outlets called emitters or drippers.
• Water is applied close to plants near the roots so that only part of the soil in which the roots grow is wetted, unlike surface and sprinkler irrigation, which involves wetting the whole soil profile. 
• Drip irrigation is known to be the most efficient irrigation methods with 95-100% water use efficiency.
• Drip irrigation is used in farms, commercial greenhouses, and residential gardens.
• Drip irrigation is adopted extensively in areas of acute water scarcity and especially for crops and trees such as coconuts, containerized landscape trees, grapes, bananas, ber, eggplant, citrus, strawberries, sugarcane, cotton, maize, and tomatoes.
