  One of the important factors which has led to reduction of the sugarcane yield is short-term water stress either in growing season or in the meantime of two sequence irrigation events. Therefore, studying and monitoring of crucial parameters of sugarcane water content (canopy temperature, soil moisture and vegetation moisture) is essential. The main objectives of present study are monitoring the effective parameters of sugarcane water content, and consequently determining the correlation between two different methods for determining irrigation schedule which are based on the canopy temperature and the leaf sheath moisture measurement, in order to have an efficient irrigation scheduling as well as determining the time and the amount of irrigation, accurately.
