Analysis of Irrigation Pumping and Application Efficiency in Nevada

摘要

Irrigated alfalfa production in Nevada is a major segment of the state's agricultural sector. However, with increasing fuel costs and variable surface water supplies, efficient allocation of water is desired. Determination of profit maximizing quantities of water for Central Nevada under different irrigation delivery and pumping efficiencies were derived. A computer irrigation cost generator from Oklahoma State University was put on the University of Nevada's main frame computer to derive irrigation costs for different electrical charges, water delivery efficiencies, and pumping efficiencies. The study indicates a potential for substantial water and cost savings with improved water delivery and pumping plant efficiencies. The irrigation strategy that may be a viable alternative to contemporary practices is to irrigate up to the first cutting and discontinue irrigation for that season.
