Question

Write two methods of irrigation.

Hint:

Drip irrigation saves 40–70% water compared to traditional surface irrigation.

Answer 1

Step 1: Recall major irrigation types.
Irrigation methods are broadly classified as surface, subsurface, and modern pressurized methods.
Step 2: Examples.
1. Surface irrigation (flood/furrow/basin): Water applied over soil surface by gravity flow.
2. Drip irrigation: Modern method delivering water drop by drop directly to root zone, saving water.
Step 3: Conclusion.
Thus, two irrigation methods are surface irrigation and drip irrigation.
