Deficit Lrrigation: Growers can manage a potato crop with less water

摘要

Irrigation is required for profitable commercial potato production in the Western United States Potatoes have a relatively shallow root zone and a lower tolerance for water stress than most other crops grown in Idaho The preference for producing thisdrought-sensitive crop in coarse-textured soils with limited water holding capacity makes precise irrigation management a necessity to obtain optimum yield and quality When restricted water availability reduces potato produc-tion potential, options for increasing water use efficiency need to be considered.
