Introduction
Irrigation efficiency is a crucial aspect of agricultural water management, particularly in optimizing water use for crop production. This analysis evaluates the application efficiency of water diverted to a field based on the given data.
Water Diverted
- Flow Rate: 12 cumec (cubic meters per second)
- Irrigation Duration: 4 hours
- Total Water Diverted:
- Convert hours to seconds: 4 hours = 14,400 seconds
- Total volume = Flow Rate x Time = 12 cumec x 14,400 seconds = 172,800 cubic meters
Field Area
- Field Size: 0.32 km²
- Convert to m²: 0.32 km² = 320,000 m²
Water Stored in Root Zone
- Soil Moisture Measurement: 0.4 m of water
- Volume of Water Stored:
- Volume = Field Area x Depth of Water = 320,000 m² x 0.4 m = 128,000 cubic meters
Application Efficiency Calculation
- Application Efficiency Formula:
- Application Efficiency = (Volume of Water Stored / Total Water Diverted) x 100
- Calculation:
- Application Efficiency = (128,000 m³ / 172,800 m³) x 100 ≈ 74.07%
Conclusion
The application efficiency of the irrigation system is approximately 74.07%. This indicates that a significant portion of the diverted water was effectively utilized for moisture retention in the root zone, demonstrating an efficient irrigation strategy. Understanding and improving application efficiency can lead to better water management practices, ensuring sustainability in agricultural production.
