A Discharge of 150 lit/sec was delieved from canal and 110 Lit /sec reached the field.In 8 hr, 2.2 Ha area was irrigated.

• Runoff Loss in the field = 445m³
• Depth of water Penetration varies Linearly from 1.5m at the head End of the field to 1.1m at the tail end.
• Effective Root Zone Depth = 1.5m Available moisture holding capacity of soil is 200mm per m depth of soil.
• Note that irrigation was started at a moisture extracted level of 50%.

Then, Find a) Nc b) Na c) Ns d) Nd

(a) $n_{c}=\frac{\text { water delivered to the Field }}{\text { (water Extracted From the source) }} \times 100$ $$ n_{c}=\frac{110 lit/ \mathrm{s}}{150 lit/ \mathrm{s}} \times 100=73.33 \% $$ (B) Application efficiency, $n_{a}=\frac{ \text { water actually stored in the Root }}{\text { water delivered to the Field }} \times 100$ …
