Sugarcane productivity is not determined only by good water availability in the soil, as is the case in most irrigated crops, but also by other factors such as soil fertility, variety with great productive potential, management of the crop, including pest control, period of cutting, etc. In Brazilian tropical and subtropical regions, sugarcane productivity in rain fed conditions can reach 100 t/ha; however, in most of the producing regions, the yield is well below this value. In irrigated cultivation, yields higher than 200 t/ha can be reached, in favorable climate conditions, with soil fertility, and adequate conduction of the crop and of the irrigation management. However, the lack of knowledge of the benefits originating from irrigation restricts the use of this technique. In sugarcane irrigation management it is important to characterize the development phases of the crop, in order to allow the adequate application of water throughout the cycle. Sugarcane presents good tolerance to water deficit, due to its physiological adjustments, as well as due to the capacity of its root system to adapt to the new conditions of water stress in the soil. In this chapter, irrigation methods in the sugarcane crop and the best practices in irrigation management are discussed.
