## **Abstract**

Applying irrigation at the right time and the correct amount is a challenge. Irrigation scheduling is a method of determining the appropriate amount of water to be applied to a crop at the correct time to achieve full crop production potential. Scheduling irrigation based on the weather, soil moisture, and plant data are reviewed. The advantages and challenges of each irrigation scheduling method are also discussed. In addition, innovative irrigation scheduling methods such as internet of things (IoT)-based on using wireless communication and smartphone app-based are described. In conclusion, the irrigation scheduling method has been continuously developed to be more accurate and precise. Integration of innovative technologies and techniques, such as IoT and machine learning, could be used to take the scheduling method to the next level.
