Abstract


The calculation of the water consumption of plants, is a guideline to manage the amount of water and the cultivation of crops.There is enough water to grow the crop,is reduce damage to farmers can be supported when drought or rain drops. The calculation of water consumption of plants can be done in a variety of method such as plant measurements using a tool the calculation of the weather data, etc. The results have a close approximation of the truth is calculated from the climate data, it will be required to use multi-area climate data and calibrate data. Therefore, this study offers an application for calculating the water consumption of the reference plants. Using 124 weather stations from Thailand's meteorological stations, the results can be used to calculate the water requirements of plants. Proposed evapotranspiration forecasts for different areas. Climate data can be manual update through the application and the evapotranspiration equation was recalculated. We use appsheet tool to create our application and connect our spreadsheet to compute evapotranspiration. It is can be calculate from the complex equation and easily to make application, easily to share the application to user.
