Low-elevation spray application (LESA) is an irrigation modification that places nozzles 1–2 ft aboveground. The lower nozzle height in LESA enables water droplets to spend less time in the air, which reduces water losses to wind drift and evaporation. LESA irrigation has seldom been investigated in potato production. This publication outlines three field experiments that were conducted in southern and eastern Idaho to evaluate potato tuber yields under LESA and traditional (MESA: mid-elevation spray application) irrigation methods. It addresses soil moisture, tuber yields, cost analysis, and conclusions and recommendations.
