Question

Distinguish between the following.

Furrow irrigation and drip irrigation.

Answer 1

Sr. No.	Feature	Furrow Irrigation	Drip Irrigation
1.	Type	Furrow irrigation is a surface, gravity-fed method.	Drip irrigation is a pressurized micro-irrigation method.
2.	Water Use Efficiency	Furrow irrigation has a lower efficiency due to losses from evaporation and runoff.	Drip irrigation achieves a much higher efficiency by minimizing those losses.
3.	Energy Requirement	Furrow irrigation requires minimal to no energy because it relies primarily on gravity.	Drip irrigation requires a pump to maintain operating pressure.
4.	Initial Investment	Furrow irrigation requires a low initial investment using basic trenching tools.	Drip irrigation involves a high initial investment for specialized piping, emitters, and filters.
5.	Weed Growth	Furrow irrigation encourages high weed growth because entire spaces between rows get wet.	Drip irrigation keeps inter-row spaces dry to maintain low weed growth.
