Question

Explain the modern methods of irrigation. (any one)

Hint:

Modern irrigation methods like drip and sprinkler systems improve water efficiency and help farmers grow better crops, even in water-scarce regions.

Answer 1

A contemporary irrigation method is:

1. Drip Irrigation:

• Description: Drip irrigation is an advanced irrigation technique that delivers water directly to plant roots in small volumes via narrow tubes, emitters, or drippers.
• Operation: - A system of pipes, valves, and emitters is positioned near plant bases. - Water is released slowly at low pressure, minimizing losses from evaporation or surface runoff. - Water is precisely applied to the root zone.
• Benefits: - Achieves water savings of 50-70%. - Mitigates soil erosion and reduces weed proliferation. - Enhances crop yields and farmer efficiency. - Effective in water-scarce arid and semi-arid zones.
• Application: Drip irrigation is extensively employed in horticulture and for cash crops such as tomatoes, cucumbers, and grapes.

2. Sprinkler Irrigation:

• Description: Sprinkler irrigation simulates rainfall by distributing water over crops through a system of pumps, pipes, and oscillating nozzles.
• Operation: - Water is propelled at high pressure through pipes to rotating sprinklers. - Sprinklers distribute water uniformly across the field.
• Benefits: - Suitable for varied topography and extensive areas. - Reduces labor requirements and conserves water compared to conventional methods. - Prevents soil erosion and promotes crop development.
• Application: Sprinkler systems are utilized for crops like wheat, sugarcane, and for maintaining grasslands.
