Decision Making for Rice Farming Based on Seasonal Forecast System
（Japan International Research Center for Agriculture Sciences：JIRCAS）
Challenges In irrigated rice cultivation of the target area, costs and waste of water resources due to over-operation of irrigation pumps are major challenges. Accurate forecast of timing and amount of rainfall enables to use stormwater and solve these problems. In the dual cropping, rainfall prediction helps to make an appropriate cultivation plan.
Solution WeRise is an ICT tool that was developed to help rice farmers make decisions. It can make seasonal forecasts up to 12 months ahead and based on that forecast, it can predict the optimum variety of crop, sowing time, fertilization time, and harvest time using a crop growth model. It is applicable for dual cropping and can improve farming plan by supporting to adjust the work schedule between two seasons.
