Popis:	Water‐use efficiency under drip‐ and furrow‐irrigation in Hawaii's sugar industry was studied. The study method consisted of a quadratic production function describing tons of sugar per acre (TSA) with respect to water use, fertilizer use, plant cycle, cane age, irrigation method used, cane varieties, harvesting months, and field characteristics. Drip irrigation in Hawaii's sugar industry was found to be a preferred alternative, resulting in yield increases of about 15% and water‐use reduction of almost 12%. This superior performance of drip over furrow irrigation was largely due to the land‐quality‐augmenting characteristics of drip technology.
