🌱 Crop Water Requirement (ETc)
What is Crop Water Requirement?
Crop Water Requirement (ETc) is the total amount of water needed by a crop for evapotranspiration during its growth period. It depends on climate and crop type.
Formula Used
ETc = ET0 × Kc
Where:
• ET0 = Reference evapotranspiration (mm)
• Kc = Crop coefficient (dimensionless)
Enter Required Data
Important Notes:
• Kc varies with crop growth stages
• ET0 is obtained from weather data or pan evaporation
• ETc is used for irrigation scheduling
