Furrow irrigation mainly practising at present for sugarcane cultivation requires a close supervision during the application of water. At night, supervision of the in-field distribution of water is not easy. It is therefore recommended that irrigation at field level be limited to daytime hours only in order to increase irrigation efficiency. However, a 12-hour water supply schedule for the entire irrigation system would extremely effect to the on-going design and construction of irrigation system. This will require to find an appropriate method of water delivery for the area with mixed cropping of sugarcane and rice. With the consideration from several alternates including economic implications and operational aspects, a 24-hour supply schedule in combination with a 12-hour irrigation schedule, and storage at lateral canal was recommended as the most suitable solution under the present situation. The research was conducted to compare the effectiveness of the selected method with a nearby system of non-exiting over night storage. Using the 3-group of indicators, it was shown that there were statistically no difference of indicating values between the two systems. In other words, the effectiveness of the overnight storage utilization can not be seen clearly under the similar system magement of both systems at present.
