Water for agricultural use accounts for a very high percentage of worldwide water consumption. In order to maximize productivity and profitability, while reducing the environmental impact of vegetable farming, growers must choose the correct irrigation system for their crop as well as determine the best methods for managing and scheduling irrigation. This chapter considers recent advances in irrigation techniques used in vegetable cultivation. It is divided into three main sections: irrigation systems, irrigation system performance, and irrigation scheduling. The author’s coverage of irrigation systems includes sprinkler irrigation, drip irrigation, surface flood/furrow irrigation, and subirrigation (including seepage irrigation, irrigation drain tiles, and subsurface drip irrigation). Irrigation system performance is then discussed in relation to efficiency, uniformity, and water-use efficiency. The section on irrigation scheduling includes irrigate anytime, “Feel and Appearance” irrigation, systematic irrigation, the crop water demand method, the soil water status method, and combined methods.
