An Excel-based computational template was developed to help Extension educators to schedule irrigation for efficient use of water. The dual crop coefficient method is employed to calculate evaporation and transpiration rates separately in the template, expecting more accurate soil water tracking compared to using a single crop coefficient. Using the template, the crop water needs can be conveniently calculated on the basis of soil characteristics, crop growth stages, and weather information. Application examples provided in electronic supplementary material demonstrate that the amount and frequency of irrigation should be adjusted according to soil texture. The template is available to Extension professionals.
