Irrigation consists of the artificial supply of water to the plants, which, together with the correct management of the crop, provides significant increases in crop productivity. Irrigated agriculture is present in all Brazilian regions, especially in periods when there is a lack of rain. The irrigation technique has been improved over time, currently having more efficient systems and less use of water. Thus, by properly using agronomic techniques together with irrigation, the plant has all the conditions to express all its genetic production potential. The definition of the adequate irrigation system must be based on aspects such as climate, topography, soil, crop that will be irrigated, financial and technological availability of the producer. Additionally, when working with irrigated agriculture it is important to define when and how much water to apply to a crop. In addition, information on crop physiology, water consumption during crop development is essential to obtain high yields and properly manage irrigation water.
