What is Crop Factor in Irrigation?

The Crop Water Need is defined as the depth (or amount) of water needed to meet the water loss through evapotranspiration, it indicates the influence of the crop type and growth stage on crop water needs: the influence of the crop is expressed in the crop factor.

What are the values of K for different crops?

The values are as under
1.Rice-1.10
2.Wheat-0.65
3.Maize-0.65
4.Sugarcane-0.90
5.Potatoes-0.70
6.Cotton-0.65
