Have I enough water to finish my rice crop?

Rice crop water use is determined by:

1. the amount of water stored in the soil profile or already ponded on bays;
2. evapo-transpiration demand as affected by weather conditions (wind, humidity, rainfall, temperature, solar radiation);
3. the duration of crop growth as affected by variety and crop growth stage;
4. soil type and permeability.

This Primefact shows you how to calculate your rice crop water needs, including the duration of the crop growing season and estimated rice crop water use.
